[InstCombine] Remove foldAndOrOfEqualityCmpsWithConstants() fold

This fold handles a special subset of foldAndOrOfICmpsUsingRanges(),
use the more generic implementation instead.

The result can differ if a representation using a range comparison
is possible, in which case that is preferred over masking. There is
a canonicalization opportunity here.
