[testsuite, i386] Fix gcc.target/i386/minmax-4.c etc. on 32-bit Solaris/x86

[Rainer Orth <ro at CeBiTec dot Uni-Bielefeld dot DE>]

The new gcc.target/i386/minmax-4.c etc. testcases currently FAIL on
32-bit Solaris/x86:

FAIL: gcc.target/i386/minmax-4.c scan-assembler-times pmaxsd 1
FAIL: gcc.target/i386/minmax-4.c scan-assembler-times pmaxud 1
FAIL: gcc.target/i386/minmax-4.c scan-assembler-times pminsd 1
FAIL: gcc.target/i386/minmax-4.c scan-assembler-times pminud 1
FAIL: gcc.target/i386/minmax-5.c scan-assembler-times vpmaxsd 1
FAIL: gcc.target/i386/minmax-5.c scan-assembler-times vpmaxud 1
FAIL: gcc.target/i386/minmax-5.c scan-assembler-times vpminsd 1
FAIL: gcc.target/i386/minmax-5.c scan-assembler-times vpminud 1
FAIL: gcc.target/i386/minmax-6.c scan-assembler pmaxsd
FAIL: gcc.target/i386/minmax-7.c scan-assembler pminsd
FAIL: gcc.target/i386/pr91154.c scan-assembler-not cmov
FAIL: gcc.target/i386/pr91154.c scan-assembler-times paddd 2
FAIL: gcc.target/i386/pr91154.c scan-assembler-times pmaxsd 2

I'd mentioned this in PRs target/91154 and target/91498 where Uros
pointed out that 32-bit Solaris/x86 only guarantees 4-byte stack
alignment, thus STV is disabled.

In line with several other STV tests, adding -mno-stackrealign to the
options fixes the failures.

Tested with the appropriate runtest invocation on i386-pc-solaris2.11
and x86_64-pc-linux-gnu.

Ok for mainline?
