[InstCombine] use m_APInt to allow icmp (binop X, Y), C folds with constant splat vectors
...
This removes the restriction for the icmp constant, but as noted by the FIXME comments,
we still need to change individual checks for binop operand constants.

[InstCombine] Fold icmp ugt/ult (udiv i32 C2, X), C1.
...
This patch adds support for two optimizations:
icmp ugt (udiv C2, X), C1 -> icmp ule X, C2/(C1+1)
icmp ult (udiv C2, X), C1 -> icmp ugt X, C2/C1
