i386: Fix up 8-byte vcond* with -mxop [PR100445]
ix86_expand_sse_movcc has special TARGET_XOP handling and the recent
addition of support of v*cond* patterns for MMXMODEI modes 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).
