This patch changes SUBREG_BYTE from an int to a poly_int.
Since valid SUBREG_BYTEs must be contained within the mode of the
SUBREG_REG, the required range is the same as for GET_MODE_SIZE,
i.e. unsigned short. The patch therefore uses poly_uint16(_pod)
for the SUBREG_BYTE.
Using poly_uint16_pod rtx fields requires a new field code ('p').
Since there are no other uses of 'p' besides SUBREG_BYTE, the patch
doesn't add an XPOLY or whatever; all uses should go via SUBREG_BYTE
instead.
The patch doesn't bother implementing 'p' support for legacy
define_peepholes, since none of the remaining ones have subregs
in their patterns.
As it happened, the rtl documentation used SUBREG as an example of a
code with mixed field types, accessed via XEXP (x, 0) and XINT (x, 1).
Since there's no direct replacement for XINT, and since people should
never use it even if there were, the patch changes the example to use
INT_LIST instead.
The patch also changes subreg-related helper functions so that they too
take and return polynomial offsets. This makes the patch quite big, but
it's mostly mechanical. The patch generally sticks to existing choices
wrt signedness.

This patch adds an rtl representation of poly_int values.
There were three possible ways of doing this:
(1) Add a new rtl code for the poly_ints themselves and store the
coefficients as trailing wide_ints. This would give constants like:
(const_poly_int [c0 c1 ... cn])
The runtime value would be:
c0 + c1 * x1 + ... + cn * xn
(2) Like (1), but use rtxes for the coefficients. This would give
constants like:
(const_poly_int [(const_int c0)
(const_int c1)
...
(const_int cn)])
although the coefficients could be const_wide_ints instead
of const_ints where appropriate.
(3) Add a new rtl code for the polynomial indeterminates,
then use them in const wrappers. A constant like c0 + c1 * x1
would then look like:
(const:M (plus:M (mult:M (const_param:M x1)
(const_int c1))
(const_int c0)))
There didn't seem to be that much to choose between them. The main
advantage of (1) is that it's a more efficient representation and
that we can refer to the cofficients directly as wide_int_storage.

This patch adds a helper routine that constructs rtxes
for constant shift amounts, given the mode of the value
being shifted. As well as helping with the SVE patches, this
is one step towards allowing CONST_INTs to have a real mode.
One long-standing problem has been to decide what the mode
of a shift count should be for arbitrary rtxes (as opposed to those
directly tied to a target pattern). Realistic choices would be
the mode of the shifted elements, word_mode, QImode, a 64-bit mode,
or the same mode as the shift optabs (in which case what should the
mode be when the target doesn't have a pattern?)
For now the patch picks a 64-bit mode, but with a ??? comment.

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
changes towards SFN.

This patch introduces a number of new macros and functions that will
be used to distinguish between different kinds of debug stmts, insns
and notes, namely, preexisting debug bind ones and to-be-introduced
nonbind markers.
In a seemingly mechanical way, it adjusts several uses of the macros
and functions, so that they refer to narrower categories when
appropriate.
These changes, by themselves, should not have any visible effect in
the compiler behavior, since the upcoming debug markers are never
created with this patch alone.

This patch is like the earlier GET_MODE_UNIT_SIZE one,
but for precisions rather than sizes. There is one behavioural
change in expand_debug_expr: we shouldn't use lowpart subregs
for non-scalar truncations, since that would just reinterpret
some of the scalars and drop the rest. (This probably doesn't
trigger in practice.) Using TRUNCATE is fine for scalars,
since simplify_gen_unary knows when a subreg can be used.

This patch adds a partial_subreg_p predicate to go alongside
paradoxical_subreg_p.
Like the paradoxical_subreg_p patch, this one replaces some tests that
were based on GET_MODE_SIZE rather than GET_MODE_PRECISION. In each
case the change should be a no-op or an improvement.
The regcprop.c patch prevents some replacements of the 82-bit RFmode
with the 80-bit XFmode on ia64. I don't understand the target details
here particularly well, but from the way the modes are described in
ia64-modes.def, it isn't valid to assume that an XFmode can carry an
RFmode payload. A comparison of the testsuite assembly output for one
target per CPU showed no other differences.
Some of the places changed here are tracking the widest access mode
found for a register. The series tries to standardise on:
if (partial_subreg_p (widest_seen, new_mode))
widest_seen = new_mode;
rather than:
if (paradoxical_subreg_p (new_mode, widest_seen))
widest_seen = new_mode;
Either would have been OK.

The new iterators are:
- FOR_EACH_MODE_IN_CLASS: iterate over all the modes in a mode class.
- FOR_EACH_MODE_FROM: iterate over all the modes in a class,
starting at a given mode.
- FOR_EACH_WIDER_MODE: iterate over all the modes in a class,
starting at the next widest mode after a given mode.
- FOR_EACH_2XWIDER_MODE: same, but considering only modes that
are two times wider than the previous mode.
- FOR_EACH_MODE_UNTIL: iterate over all the modes in a class until
a given mode is reached.
- FOR_EACH_MODE: iterate over all the modes in a class between
two given modes, inclusive of the first but not the second.
These help with the stronger type checking added by later patches,
since every new mode will be in the same class as the previous one.

This patch makes more use of the existing paradoxical_subreg_p
predicate and also adds a version that operates on outer and
inner modes.
Some of the affected tests were based on GET_MODE_SIZE rather than
GET_MODE_PRECISION and so the patch could change the result for modes
that have the same size but different precisions. I think in each
case the change should be a no-op or more correct, since a mode with
precision N bits can't be expected to hold all of a mode with precision
M>N bits.
The patch changes the branch taken in simplify_subreg for modes with
equal precision, but the new form matches the commentary more closely.
Both branches should be equally good in that situation.

LOAD_EXTEND_OP only applies to scalar integer modes that are narrower
than a word. However, callers weren't consistent about which of these
checks they made beforehand, and also weren't consistent about whether
"smaller" was based on (bit)size or precision (IMO it's the latter).
This patch adds a wrapper to try to make the macro easier to use.
LOAD_EXTEND_OP is often used to disable transformations that aren't
beneficial when extends from memory are free, so being stricter about
the check accidentally exposed more optimisation opportunities.
"SUBREG_BYTE (...) == 0" and subreg_lowpart_p are implied by
paradoxical_subreg_p, so the patch also removes some redundant tests.
The patch doesn't change reload, since different checks could have
unforeseen consequences.

While changing LABEL_REF_LABEL it might as well become an inline
function, so that its clearer what types are involved. Unfortunately
because it is still possible to use XEXP and related macros on a
LABEL_REF rtx you can still set the field to be a non insn rtx. The
other unfortunate thing is that the generators actually create LABEL_REF
rtx that refer to MATCH_x rtx, so there we actually need to use XEXP to
bypass the checking this patch adds.

This patch replaces all uses of CONST_DOUBLE_FROM_REAL_VALUE
with the already-existing const_double_from_real_value.
Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested by
building one target per CPU directory and checking that there were
no new warnings and no changes in testsuite output at -O2.
