Fix m68k-linux-gnu libgcc build for ColdFire (PR target/68467).
PR target/68467 is libgcc failing to build for m68k-linux-gnu
configured for ColdFire.
Jeff has an analysis in the PR identifying the problem as resulting
from the callers of libcalls with 1-byte or 2-byte arguments wanting
to push just 1 or 2 bytes on the stack, while the libcall
implementations have the normal C ABI and expect 4-byte arguments.
For normal C functions, I believe the TARGET_PROMOTE_PROTOTYPES
definition would ensure such arguments get passed as 4-byte, but that
does not apply for libcalls.
This patch fixes the issue by defining TARGET_PROMOTE_FUNCTION_MODE
for m68k. The definition is conservative, only applying promotions in
the case of arguments to libcalls; otherwise it returns the unpromoted
type, which I believe matches what the default implementation of the
hook would have done on m68k.
I have tested that this fixes the libgcc build for ColdFire, and, in
conjunction with one glibc patch, this enables glibc to build cleanly
for ColdFire and to pass the compilation parts of the glibc testsuite
except for one test unrelated to this patch (while glibc and the
compilation parts of the testsuite continue to build OK for
non-ColdFire m68k, as expected). I have *not* run any GCC tests for
this patch, or any execution tests for m68k.

Remove explicit dg-do runs from gcc.dg/vect (PR 83889)
The failures in this PR were from forcing { dg-do run } even when

The default vect.exp behaviour is to execute when possible, so there's
no need for a dg-do at all.
The patch removes other unconditional { dg-do run }s too. Many of them
were already failing in the same way.
Also, the dg-do run condition in vect-reduc-or* seems unnecessary:

[testsuite] Fix arm options in gcc.dg/lto/
20110201-1_0.c
This test fails on arm hardfloat targets because it sets an explicit -mfloat-abi=softfp.
The usual approach to setting the NEON options is to use dg-add-options arm_neon.
But in the lto tests we don't have that framework, we can only set them explicitly with dg-lto-options.
The solution is to remove the explicit -mfloat-abi=softfp and instead add an effective target check
for arm_neon_ok_no_float_abi that makes sure we only run this test if -mfpu=neon is enough to get NEON
without any -mfloat-abi options. In fact, this is what the comment above check_effective_target_arm_neon_ok_no_float_abi_nocache
recommends for lto tests.
That way on my hardfloat toolchain the test doesn't try to link the softfp binary against a hard-float runtime/test glue
and all is good. I've tested that the test is appropriately skipped when testing a --with-float=soft toolchain.

-Warray-bounds: Fix false positive in some "switch" stmts (PR tree-optimization/83510)
PR tree-optimization/83510 reports that r255649 (for
PR tree-optimization/83312) introduced a false positive for
-Warray-bounds for array accesses within certain switch statements:
those for which value-ranges allow more than one case to be reachable,
but for which one or more of the VR-unreachable cases contain
out-of-range array accesses.
In the reproducer, after the switch in f is inlined into g, we have 3 cases
for the switch (case 9, case 10-19, and default), within a loop that
ranges from 0..9.
With both the old and new code, vr_values::simplify_switch_using_ranges clears
the EDGE_EXECUTABLE flag on the edge to the "case 10-19" block. This
happens during the dom walk within the substitute_and_fold_engine.
With the old code, the clearing of that EDGE_EXECUTABLE flag led to the
/* Skip blocks that were found to be unreachable. */
code in the old implementation of vrp_prop::check_all_array_refs skipping
the "case 10-19" block.
With the new code, we have a second dom walk, and that dom_walker's ctor
sets all edges to be EDGE_EXECUTABLE, losing that information.
Then, dom_walker::before_dom_children (here, the subclass'
check_array_bounds_dom_walker::before_dom_children) can return one edge, if
there's a unique successor edge, and dom_walker::walk filters the dom walk
to just that edge.
Here we have two VR-valid edges (case 9 and default), and an VR-invalid
successor edge (case 10-19). There's no *unique* valid successor edge,
and hence taken_edge is NULL, and the filtering in dom_walker::walk
doesn't fire.
Hence we've lost the filtering of the "case 10-19" BB, hence the false
positive.
The issue is that we have two dom walks: first within vr_values'
substitute_and_fold_dom_walker (which has skip_unreachable_blocks == false),
then another within vrp_prop::check_all_array_refs (with
skip_unreachable_blocks == true).
Each has different "knowledge" about ruling out edges due to value-ranges,
but we aren't combining that information. The former "knows" about
out-edges at a particular control construct (e.g. at a switch), the latter
"knows" about dominance, but only about unique successors (hence the
problem when two out of three switch cases are valid).
This patch combines the information by preserving the EDGE_EXECUTABLE
flags from the first dom walk, and using it in the second dom walk,
potentially rejecting additional edges.
Doing so fixes the false positive.
I attempted an alternative fix, merging the two dom walks into one, but
that led to crashes in identify_jump_threads, so I went with this, as
a less invasive fix.

[arm] Make gcc.target/arm/copysign_softfloat_1.c more robust
This test has needlessly restrictive requirements. It tries to force a soft-float target and tries to run.
This makes it unsupportable for any non-soft-float variant.
In fact, the test can be a run-time test for any target, and only the scan-assembler tests are specific to
-mfloat-abi=soft. So this patch makes the test always runnable and makes the scan-assembler checks predicable
on the the new arm_sotftfloat effective target check.

Fix vect_def_type handling in x86 scatter support (PR 83940)
As Jakub says in the PR, the problem here was that the x86/built-in
version of the scatter support was using a bogus scatter_src_dt
when calling vect_get_vec_def_for_stmt_copy (and had since it
was added). The patch uses the vect_def_type from the original
call to vect_is_simple_use instead.
However, Jakub also pointed out that other parts of the load and store
code passed the vector operand rather than the scalar operand to
vect_is_simple_use. That probably works most of the time since
a constant scalar operand should give a constant vector operand,
and likewise for external and internal definitions. But it
definitely seems more robust to pass the scalar operand.
The patch avoids the issue for gather and scatter offsets by
using the cached gs_info.offset_dt. This is safe because gathers
and scatters are never grouped, so there's only one statement operand
to consider. The patch also caches the vect_def_type for mask operands,
which is safe because grouped masked operations share the same mask.
That just leaves the store rhs. We still need to recalculate the
vect_def_type there since different store values in the group can
have different definition types. But since we still have access
to the original scalar operand, it seems better to use that instead.
