    i386: Fix up V2SFmode vcond* with -mxop [PR100581]

    ix86_expand_sse_movcc has special TARGET_XOP handling and the recent
    addition of support of v*cond* patterns for V2SFmode results in
    ICEs because the expected pattern doesn't exist.  We can handle it
    using 128-bit vpcmov (if we ignore the upper 64 bits like we ignore in
    other TARGET_MMX_WITH_SSE support).
