The test FAILs on i686-linux with:
FAIL: g++.dg/pr91838.C (test for excess errors)
Excess errors:
/home/jakub/src/gcc/gcc/testsuite/g++.dg/pr91838.C:7:8: warning: MMX vector return without MMX enabled changes the ABI [-Wpsabi]
/home/jakub/src/gcc/gcc/testsuite/g++.dg/pr91838.C:7:3: warning: MMX vector argument without MMX enabled changes the ABI [-Wpsabi]
and on x86_64-linux with -m32 testing with failure to match the
expected pattern in there (or both with e.g. -m32/-mno-mmx/-mno-sse testing).
The test is also in a wrong directory, has non-standard specification that
it requires c++11 or later.

* g++.dg/pr91838.C: Moved to ...
* g++.dg/opt/pr91838.C: ... here. Require c++11 target instead of
dg-skip-if for c++98. Pass -Wno-psabi -w to avoid psabi style
warnings on vector arg passing or return. Add -masm=att on i?86/x86_64.
Only check for pxor %xmm0, %xmm0 on lp64 i?86/x86_64.
