mode_for_int_vector, like mode_for_vector, can sometimes return
an integer mode or an unsupported vector mode. But no callers
are interested in that case, and only want supported vector modes.
This patch therefore replaces mode_for_int_vector with
related_int_vector_mode, which gives the target a chance to pick
its preferred vector mode for the given element mode and size.

This patch is the first of a series that tries to remove two
assumptions:
(1) that all vectors involved in vectorisation must be the same size
(2) that there is only one vector mode for a given element mode and
number of elements
Relaxing (1) helps with targets that support multiple vector sizes or
that require the number of elements to stay the same. E.g. if we're
vectorising code that operates on narrow and wide elements, and the
narrow elements use 64-bit vectors, then on AArch64 it would normally
be better to use 128-bit vectors rather than pairs of 64-bit vectors
for the wide elements.
Relaxing (2) makes it possible for -msve-vector-bits=128 to produce
fixed-length code for SVE. It also allows unpacked/half-size SVE
vectors to work with -msve-vector-bits=256.
The patch adds a new hook that targets can use to control how we
move from one vector mode to another. The hook takes a starting vector
mode, a new element mode, and (optionally) a new number of elements.
The flexibility needed for (1) comes in when the number of elements
isn't specified.
All callers in this patch specify the number of elements, but a later
vectoriser patch doesn't.

This patch makes compute_record_mode handle SVE vectors in the
same way as it would handle fixed-length vectors. There should
be no change in behaviour for other targets.
This is needed for the SVE equivalent of arm_neon.h types like
int8x8x2_t (i.e. a pair of int8x8_ts).

This patch generalises various places that used hwi tree accessors so
that they can handle poly_ints instead. In many cases these changes
are by inspection rather than because something had shown them to be
necessary.
I think the alias.c part is a minor bug fix: previously we used
fits_uhwi_p for a signed HOST_WIDE_INT (which the caller does
treat as signed rather than unsigned). We also checked whether
each individual offset overflowed but didn't check whether the
sum did.

So far we've used integer modes for LD[234] and ST[234] arrays.
That doesn't scale well to SVE, since the sizes aren't fixed at
compile time (and even if they were, we wouldn't want integers
to be so wide).
This patch lets the target use double-, triple- and quadruple-length
vectors instead.

This patch adds a new mode class to represent vectors of booleans.
GET_MODE_BITSIZE (m) / GET_MODE_NUNITS (m) determines the number
of bits that are used to represent each boolean; this can be 1
for a fully-packed representation or greater than 1 for an unpacked
representation. In the latter case, the value of bits other than
the lowest is not significant.
These are used by the SVE port to represent predicates.

This patch changes TYPE_VECTOR_SUBPARTS to a poly_uint64. The value is
encoded in the 10-bit precision field and was previously always stored
as a simple log2 value. The challenge was to use this 10 bits to
encode the number of elements in variable-length vectors, so that
we didn't need to increase the size of the tree.
In practice the number of vector elements should always have the form
N + N * X (where X is the runtime value), and as for constant-length
vectors, N must be a power of 2 (even though X itself might not be).
The patch therefore uses the low 8 bits to encode log2(N) and bit
8 to select between constant-length and variable-length vectors.
Targets without variable-length vectors continue to use the old scheme.
A new valid_vector_subparts_p function tests whether a given number
of elements can be encoded. This is false for the vector modes that
represent an LD3 or ST3 vector triple (which we want to treat as arrays
of vectors rather than single vectors).
Most of the patch is mechanical; previous patches handled the changes
that weren't entirely straightforward.

This patch adds a tree representation for poly_ints. Unlike the
rtx version, the coefficients are INTEGER_CSTs rather than plain
integers, so that we can easily access them as poly_widest_ints
and poly_offset_ints.
The patch also adjusts some places that previously
relied on "constant" meaning "INTEGER_CST". It also makes
sure that the TYPE_SIZE agrees with the TYPE_SIZE_UNIT for
vector booleans, given the existing:
/* Several boolean vector elements may fit in a single unit. */
if (VECTOR_BOOLEAN_TYPE_P (type)
&& type->type_common.mode != BLKmode)
TYPE_SIZE_UNIT (type)
= size_int (GET_MODE_SIZE (type->type_common.mode));
else
TYPE_SIZE_UNIT (type) = int_const_binop (MULT_EXPR,
TYPE_SIZE_UNIT (innertype),
size_int (nunits));

The wide_int routines allow things like:
wi::add (t, 1)
to add 1 to an INTEGER_CST T in its native precision. But we also have:
wi::to_offset (t) // Treat T as an offset_int
wi::to_widest (t) // Treat T as a widest_int
Recently we also gained:
wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC
This patch therefore requires:
wi::to_wide (t)
when operating on INTEGER_CSTs in their native precision. This is
just as efficient, and makes it clearer that a deliberate choice is
being made to treat the tree as a wide_int in its native precision.
This also removes the inconsistency that
a) INTEGER_CSTs in their native precision can be used without an accessor
but must use wi:: functions instead of C++ operators
b) the other forms need an explicit accessor but the result can be used
with C++ operators.
It also helps with SVE, where there's the additional possibility
that the tree could be a runtime value.

integer equivalent of an existing mode. This patch adds helpers
for doing that.

...to make it consistent with int_mode_for_size etc.
require () seems like the right choice in replace_reg_with_saved_mem
because we use the chosen mode for saving and restoring registers,
which cannot be done in BLKmode. Similarly require () seems like
the right choice in calls related to secondary memory reloads (the ones
in config/, and in get_secondary_mem) because the reload must always
have a defined mode, which e.g. determines the size of the slot.
We can use require () in simplify_subreg_concatn and assemble_integer
because it isn't meaningful to create a subreg with BLKmode (for one
thing, we couldn't tell then whether it was partial, paradoxical, etc.).
make_fract_type and make_accum_type must find a mode because that's
what distinguishes accumulator FIXED_POINT_TYPEs from fractional
FIXED_POINT_TYPEs.

This patch converts more places that could use int_mode_for_size instead
of mode_for_size. This is in preparation for an upcoming patch that
makes mode_for_size itself return an opt_mode.
require () seems like the right choice in expand_builtin_powi
because we have got past the point of backing out. We go on to do:
op1 = expand_expr (arg1, NULL_RTX, mode2, EXPAND_NORMAL);
if (GET_MODE (op1) != mode2)
op1 = convert_to_mode (mode2, op1, 0);
which would be invalid for (and have failed for) BLKmode.
In get_builtin_sync_mode and expand_ifn_atomic_compare_exchange,
the possible bitsizes are {8, 16, 32, 64, 128}, all of which give
target-independent integer modes (up to TImode). The comment above
the call in get_builtin_sync_mode makes clear that an integer mode
must be found.
We can use require () in expand_builtin_atomic_clear and
expand_builtin_atomic_test_and_set because there's always an integer
mode for the boolean type. The same goes for the POINTER_SIZE request
in layout_type. Similarly we can use require () in combine_instructions
and gen_lowpart_common because there's always an integer mode for
HOST_BITS_PER_WIDE_INT (DImode when BITS_PER_UNIT == 8), and
HOST_BITS_PER_DOUBLE_INT (TImode).
The calls in aarch64_function_value, arm_function_value,
aapcs_allocate_return_reg and mips_function_value_1 are handling
cases in which a big-endian target passes or returns values at
the most significant end of a register. In each case the ABI
constrains the size to a small amount and does not handle
non-power-of-2 sizes wider than a word.
The calls in c6x_expand_movmem, i386.c:emit_memset,
lm32_block_move_inline, microblaze_block_move_straight and
mips_block_move_straight are dealing with expansions of
block memory operations using register-wise operations,
and those registers must have non-BLK mode.
The reason for using require () in ix86_expand_sse_cmp,
mips_expand_ins_as_unaligned_store, spu.c:adjust_operand and
spu_emit_branch_and_set is that we go on to emit non-call
instructions that use registers of that mode, which wouldn't
be valid for BLKmode.

This patch uses scalar_mode in a few miscellaneous places:
- Previous patches mean mode_to_vector can take a scalar_mode without
further changes.
- Implicit promotion is limited to scalar types (affects promote_mode
and sdbout_parms)

This patch adds a SCALAR_TYPE_MODE macro, along the same lines as
SCALAR_INT_TYPE_MODE and SCALAR_FLOAT_TYPE_MODE. It also adds
two instances of as_a <scalar_mode> to c_common_type, when converting
an unsigned fixed-point SCALAR_TYPE_MODE to the equivalent signed mode.

This patch changes the types of various things from machine_mode
to scalar_int_mode, in cases where (after previous patches)
simply changing the type is enough on its own. The patch does
nothing other than that.

This patch uses opt_scalar_int_mode rather than machine_mode
when iterating over scalar_int_modes, in cases where that helps
with future patches. (Using machine_mode is still OK in places
that don't really care about the mode being a scalar integer.)

get_best_mode always returns a scalar_int_mode on success,
so this patch makes that explicit in the type system. Also,
the "largest_mode" argument is used simply to provide a maximum
size, and in practice that size is always a compile-time constant,
even when the concept of variable-sized modes is added later.
The patch therefore passes the size directly.

This patch replaces checks of "SCALAR_INT_MODE_P (...)" with
"is_a <scalar_int_mode> (..., &var)" in cases where it becomes
useful to refer to the mode as a scalar_int_mode. It also
replaces some checks for the two constituent classes (MODE_INT
and MODE_PARTIAL_INT).
The patch also introduces is_a <scalar_int_mode> checks for some
uses of HWI_COMPUTABLE_MODE_P, which is a subcondition of
SCALAR_INT_MODE_P.

(int_)mode_for_size, smallest_mode_for_size always returns
