    testsuite: Fix up pr91838.C test [PR91838]
    
    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/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.
