libgo: adapt Solaris 12 references

    With the change in the Solaris release model (no more major releases
    like Solaris 12 but only minor ones like 11.4), the Solaris 12
    references in GCC need to be adapted.

[Patch AArch64] Stop generating BSL for simple integer code

Turn aarch64_simd_bsldi_internal in to an insn_and_split that
knows to split back to integer operations if the register allocation
falls that way. Do this to avoid having to move between integer and

[testsuite/ARM] Consolidate sources for cmse tests

For the most part, testcases under gcc.target/arm/cmse/baseline and
gcc.target/arm/cmse/mainline are duplicate copies with only different
dejagnu directives. Although there is no requirement for them to be
similar, having them both identical allow to compare the code generated
and make it easier in case of change in code generation to both
architecture to update the testcases (if one needs updating so does the
other).

Similarly all the tests in gcc.target/arm/cmse/mainline/<floatabi> have
the same source but are duplicate copies.

This patch moves all the code in the tests to a parent directory:
gcc.target/arm/cmse for tests shared by Armv8-M Baseline and Mainline
and gcc.target/arm/cmse/mainline for tests *only* shared by the various
float ABI of Armv8-M Mainline. C includes are then used where the code
used to sit.

Note that the cmse-13.c test used to differ slightly between
architectures and float ABI tested in the first floating-point constant
passed to bar: sometimes 1.0 and sometimes 3.0. This patch settles on
3.0 to not confuse with the 1.0 constant used to clear VFP registers in
some of the configurations.

[testsuite] Fix retrieval of testname

When gcc-dg-runtest is used to run a test the test is run several times
with different options. For clarity of the log, the test infrastructure
then append the options to the testname. This means that all the code
that must deal with the testcase itself (eg. removing the output files
after the test has run) needs to remove the option name.

There is already a pattern (see below) for this in several place of the
testsuite framework but it is also missing in many places. This patch
fixes all of these places. The pattern is as follows:

set testcase [testname-for-summary]
; The name might include a list of options; extract the file name.
set testcase [lindex $testcase 0]

[ARM] Fix cmse_nonsecure_entry return insn size

A number of instructions are output in assembler form by
output_return_instruction () when compiling a function with the
cmse_nonsecure_entry attribute for Armv8-M Mainline with hardfloat float
ABI. However, the corresponding thumb2_cmse_entry_return insn pattern
does not account for all these instructions in its computing of the
length of the instruction.

This may lead GCC to use the wrong branching instruction due to
incorrect computation of the offset between the branch instruction's
address and the target address.

This commit fixes the mismatch between what output_return_instruction ()
does and what the pattern think it does and adds a note warning about
mismatch in the affected functions' heading comments to ensure code does
not get out of sync again.

Note: no test is provided because the C testcase is fragile (only works
on GCC 6) and the extracted RTL test fails to compile due to bugs in the
RTL frontend (PR82815 and PR82817)

rs6000: Separate shrink-wrapping for the TOC register

This makes the TOC register save a component.  If -msave-toc-indirect
is not explicitly disabled, it enables it, and then moves the prologue
code generated for that to a better place.  So far this only matters
for indirect calls (for direct calls the save is done in the PLT stub).
The restore is always done directly after the bl insn (the compiler
generates a nop there, the linker replaces it with a load).

Add a vect_align_stack_vars target selector

This patch adds a target selector to say whether it's possible to
align a local variable to the target's preferred vector alignment.
This can be false for large vectors if the alignment is only
a preference and not a hard requirement (and thus if there is no
need to support a stack realignment mechanism).

Add a vect_unaligned_possible target selector

This patch adds a target selector that says whether we can ever
generate an "unaligned" accesses, where "unaligned" is relative
to the target's preferred vector alignment.  This is already true if:

   vect_no_align && { ! vect_hw_misalign }

i.e. if the target doesn't have any alignment mechanism and also
doesn't allow unaligned accesses.  It is also true (for the things
tested by gcc.dg/vect) if the target only wants things to be aligned
to an element; in that case every normal scalar access is "vector aligned".
