testsuite: i386: Fix gcc.target/i386/pr82142?.c etc. on Solaris/x86
Three tests FAIL on Solaris/x86 in similar ways:
FAIL: gcc.target/i386/pr111673.c check-function-bodies advance
FAIL: gcc.target/i386/pr82142a.c check-function-bodies assignzero
FAIL: gcc.target/i386/pr82142b.c check-function-bodies assignzero
All tests FAIL as is because they lack either or both of the .LFB0 label
and the .cfi_startproc directive:
* The 32-bit pr82142b.c test lacks both, whether as or gas is in use: as
lacks full support for the cfi directives and the .LFB0 label is only
emitted with -fasynchronous-unwind-tables.
* The 64-bit tests pr111673.c and pr82142a.c already work with gas, but
with as the cfi directives are again missing.
In addition, the 32-bit test (pr82142b.c) still FAILs because 32-bit
Solaris/x86 defaults to -mstackrealign.
To fix all this, this patch adds -fasynchronous-unwind-tables
-fdwarf2-cfi-asm to all tests to force the generation of both the .LFB0
label and .cfi_startproc (which is ok since they are compile tests). In
addition, pr82142b.c is compiled with -mno-stackrealign to avoid
platform differences.
Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.
