The test FAILs on powerpc64-linux with -m32 due to psabi warnings.
Furthermore, the test needs really -msse2 to reproduce on x86 -m32 at -O2.
Fixed thusly, tested on x86_64-linux and powerpc64-linux -m32/-m64 and on
the former -m32/-mno-sse too, committed to trunk as obvious.

* gcc.dg/torture/pr94482.c: Add -Wno-psabi -w. Don't add -msse
and sse_runtime effective target on x86, instead only add -msse2
if target is sse2_runtime.
