i386: Do not emit mask compares for mode sizes < 16 [PR100445]
Recent addition of v*cond* patterns for MMXMODEI modes allows 64bit MMX
modes to enter ix86_expand_sse_cmp. ix86_use_mask_cmp_p was not prepared
to reject mode sizes < 16, resulting in ICE due to unavailability of 64bit
masked PCOM instructions.
