[X86] SimplifyDemandedBitsForTargetNode - PCMPGT(0,X) only demands the signbit of X (#163981)
PCMPGT(0,X) is a sign-splat pattern - we only need the signbit of X
The vector-compress.ll simplification is a side effect of the inner
SimplifyDemandedBits call passing through the DemandedElts mask, only
demanding the lowest 4 elements of a legalised v16i8 type.
