Fix availability compute during VN DOM elimination
This fixes an issue with redundant store elimination in FRE/PRE
which, when invoked by the DOM elimination walk, ends up using
possibly stale availability data from the RPO walk. It also
fixes a missed optimization during valueization of addresses
by making sure to use get_addr_base_and_unit_offset_1 which can
valueize and adjusting that to also valueize ARRAY_REFs low-bound.

extend DECL_GIMPLE_REG_P to all types
This extends DECL_GIMPLE_REG_P to all types so we can clear
TREE_ADDRESSABLE even for integers with partial defs, not just
complex and vector variables. To make that transition easier
the patch inverts DECL_GIMPLE_REG_P to DECL_NOT_GIMPLE_REG_P
since that makes the default the current state for all other
types besides complex and vectors.
For the testcase in PR94703 we're able to expand the partial
def'ed local integer to a register then, producing a single
movl rather than going through the stack.
On i?86 this execute FAILs gcc.dg/torture/pr71522.c because
we now expand a round-trip through a long double automatic var
to a register fld/fst which normalizes the value. For that
during RTL expansion we're looking for problematic punnings
of decls and avoid pseudos for those - I chose integer or
BLKmode accesses on decls with modes where precision doesn't
match bitsize which covers the XFmode case.

(r10-6357): we hit
26530 gcc_assert (cxx_dialect >= cxx11

and TYPE is a record type. The problem is that the argument to
value_dependent_expression_p does not satisfy potential_constant_expression
which it must, as the comment explains. I thought about fixing this in
uses_template_parms -- only call v_d_e_p if p_c_e is true, but in this
case we want to also suppress the warnings if we don't have a constant
expression. I couldn't simply check TREE_CONSTANT as in
compute_array_index_type_loc, because then we'd stop warning in the new
Wtype-limits3.C test.
Fixed by using type_dependent_expression_p_push instead. This means
that we won't suppress the warnings for value-dependent expressions that
aren't type-dependent, e.g. sizeof (T). This only seems to make a
difference for -Wdiv-by-zero, now tested in Wdiv-by-zero-3.C, where I
think it's reasonable to warn. It could make -Wtautological-compare
warn more, but that warning doesn't trigger when it gets constant arguments.
Wtype-limits4.C is a test reduced from poly-int.h and it tests a scenario
that was missing in our testsuite.
This patch also moves the warning_sentinels after the RECURs -- we mean
to use them for build_x_binary_op purposes only.

construct the result requires scope destruction, which is represented by
a TARGET_EXPR with a clean-up, and a CLEANUP_POINT_EXPR at the
location where the temporaries logically go out of scope. The reason
for this not working is because the lowering of cleanup point
expressions does not traverse inside BIND_EXPRs to expand any gimple
cleanup expressions within.
The use of creating BIND_EXPR has been removed at both locations, and

x86: Fix vextract* masked patterns [PR93069]
The AVX512F documentation clearly states that in instructions where the
destination is a memory only merging-masking is possible, not zero-masking,
and the assembler enforces that.
The testcase in this patch fails to assemble because of
Error: unsupported masking for `vextracti32x8'
on
vextracti32x8 $0x0, %zmm1, -64(%rsp){%k1}{z}
For the vector extraction patterns, we apparently have 7 *_maskm patterns
that only accept memory destinations and rtx_equal_p merge-masking source
for it, 7 *<mask_name> corresponding patterns that allow memory destination
only for the non-masked cases (through <store_mask_constraint>), then 2
*<mask_name> patterns (lo ssehalf V16FI and lo ssehalf VI8F_256 ones) which
do allow memory destination even for masked cases and are the cause of the
testsuite failure, because we must not allow C constraint if the destination
is m, and finally one pair of patterns (separate * and *_mask, hi ssehalf
VI4F_256), which has another issue (for which I don't have a testcase
though), where if it would match zero-masking with register destination,
it wouldn't emit the needed {z} into assembly.
The attached patch fixes those 3 issues only, perhaps more suitable for
backporting.
But, even with that fixed, we are missing 3 further *_maskm patterns and
more importantly, I find the split into 3 separate patterns after subst,
*_maskm for masking with memory destination, *_mask for masking with
register destination and * for non-masking unnecessarily complex and harder
for reload, so the included patch below (non-attached) instead kills all
*_maskm patterns and splits the *<mask_name> patterns into * and *_mask
by hand instead of subst, where the *_mask ones make sure that with v
destination they use 0C, while with m destination they use 0 and as
condition enforce that either destination is not MEM, or rtx_equal_p between
the destination and corresponding merging-masking operand source.
If we had those 3 missing *_maskm patterns, this patch would actually result
in both shorter sse.md and shorter machine description after subst (e.g.
length of tmp-mddump.md), as we don't have them, the patch is actually 16
lines longer sse.md, but still shorter tmp-mddump.md.

The reference to TGCware on the binaries page is gone because they only

The note about configuring 64-bit Solaris/SPARC compilers with
--build=sparcv9-sun-solaris2.11 became necessary because upstream
config.guess silently reverted my patch to automatically detect this. We
already had a bug report about a comparison failure caused by this issue.

PRU: Remove TARGET_HARD_REGNO_CALL_PART_CLOBBERED
Per clarification in [1], macro is supposed to check for partial
clobbering of single HW registers. Since PRU declares only 8-bit
HW registers, and ABI does not define individual bit clobbering,
it is safe to remove the implementation.

PRU: Fix R3.w0 register class
TI has clarified [1] that R3.w0 is caller saved, so allow compiler to
use it. This is safe change because older GCC versions treat R3.w0 as
fixed register and never use it.
