This patch implements location wrapper nodes, preserving source locations
of the uses of variables and constants in various places in the
C++ frontend: at the arguments at callsites, and for typeid, alignof,
sizeof, and offsetof.
For example, it allows the C++ FE to underline the pertinent argument
for mismatching calls, for such expressions, improving:
extern int callee (int one, const char *two, float three);
int caller (int first, int second, float third)
{
return callee (first, second, third);
}
from
test.cc: In function 'int caller(int, int, float)':
test.cc:5:38: error: invalid conversion from 'int' to 'const char*' [-fpermissive]
return callee (first, second, third);
^
test.cc:1:41: note: initializing argument 2 of 'int callee(int, const char*, float)'
extern int callee (int one, const char *two, float three);
~~~~~~~~~~~~^~~
to:
test.cc: In function 'int caller(int, int, float)':

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 changes GET_MODE_NUNITS from unsigned char
to poly_uint16, although it remains a macro when compiling
target code with NUM_POLY_INT_COEFFS == 1.
We can handle permuted loads and stores for variable nunits if
the number of statements is a power of 2, but not otherwise.
The to_constant call in make_vector_type goes away in a later patch.

This patch makes vectorizable_reduction cope with variable-length vectors.
We can handle the simple case of an inner loop reduction for which
the target has native support for the epilogue operation. For now we
punt on other cases, but patches after the main SVE submission allow
SLP and double reductions too.

This patch changes the type of current_vector_size to poly_uint64.
It also changes TARGET_AUTOVECTORIZE_VECTOR_SIZES so that it fills
in a vector of possible sizes (as poly_uint64s) instead of returning
a bitmask. The documentation claimed that the hook didn't need to
include the default vector size (returned by preferred_simd_mode),
but that wasn't consistent with the omp-low.c usage.

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));

This patch completes the infrastructure for the introduction of
statement frontiers in C-family languages.
It brings in all the code remaining code needed to introduce and
transform begin stmt trees, gimple stmts, insns and notes, and
ultimately use them to generate the is_stmt column in DWARF2+ line
number tables/programs, however none of it is activated: the option
that would do so will be introduced in a subsequent patch.
This patch depends on an earlier patch with not-quite-boilerplate

This patch makes various bits of code operate directly on the new
VECTOR_CST encoding, instead of using VECTOR_CST_ELT on all elements
of the vector.
Previous patches handled operations that produce a new VECTOR_CST,
while this patch handles things like predicates. It also makes
print_node dump the encoding instead of the full vector that
the encoding represents.

This patch uses a simple compression scheme to represent the contents
of a VECTOR_CST using its leading elements. There are three formats:
1) a repeating sequence of N values. This is encoded using the first
N elements.
2) a "foreground" sequence of N values inserted at the beginning of
a "background" repeating sequence of N values, such as:
{ 1, 2, 0, 0, 0, 0, ... }. This is encoded using the first 2*N
elements.
2) a "foreground" sequence of N values inserted at the beginning of
a "background" repeating sequence of N interleaved linear series,
such as: { 0, 0, 8, 10, 9, 11, 10, 12, ... }. This is encoded
using the first 3*N elements. In practice the foreground values
are often part of the same series as the background values,
such as: { 1, 11, 2, 12, 3, 13, ... }.
This reduces the amount of work involved in processing simple
vector constants and means that the encoding extends naturally
to variable-length vectors.

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.

This patch makes build_vector take the elements as a vec<> rather
than a tree *. This is useful for SVE because it bundles the number
of elements with the elements themselves, and enforces the fact that
the number is constant. Also, I think things like the folds can be used
with any generic GNU vector, not just those that match machine vectors,
so the arguments to XALLOCAVEC had no clear limit.

Previously VECTOR_CST_NELTS (t) read the number of elements from
TYPE_VECTOR_SUBPARTS (TREE_TYPE (t)). There were two ways of handling
this with variable TYPE_VECTOR_SUBPARTS: either forcibly convert the
number to a constant (which is doable) or store the number directly
in the VECTOR_CST. The latter seemed better, since it involves less
pointer chasing and since the tree_node u field is otherwise unused
for VECTOR_CST. It would still be easy to switch to the former in
future if we need to free up the field for someting else.
The patch also changes various bits of VECTOR_CST code to use
VECTOR_CST_NELTS instead of TYPE_VECTOR_SUBPARTS when iterating
over VECTOR_CST_ELTs. Also, when the two are checked for equality,
the patch prefers to read VECTOR_CST_NELTS (which must be constant)
and check against TYPE_VECTOR_SUBPARTS, instead of the other way
around.

This patch adds asserting as_a <scalar_int_mode> conversions
to contexts in which the input is known to be a scalar integer mode.
In expand_divmod, op1 is always a scalar_int_mode if
op1_is_constant (but might not be otherwise).
In expand_binop, the patch reverses a < comparison in order to
avoid splitting a long line.

This patch adds a SCALAR_INT_TYPE_MODE macro that asserts
that the type has a scalar integer mode and returns it as
a scalar_int_mode.

Replace checks of "GET_MODE_CLASS (...) == MODE_INT" with
"is_int_mode (..., &var)", in cases where it becomes useful
to refer to the mode as a scalar_int_mode.
