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.

	gcc/testsuite:
	* gcc.target/i386/pr111673.c (dg-options): Add
	-fasynchronous-unwind-tables -fdwarf2-cfi-asm.
	* gcc.target/i386/pr82142a.c: Likewise.
	* gcc.target/i386/pr82142b.c (dg-options): Add -mno-stackrealign
	-fasynchronous-unwind-tables -fdwarf2-cfi-asm.
