MATCH: Add `a == b | a cmp b` and `a != b & a cmp b` simplifications
Even though these are done by combine_comparisons, we can add them to match
to allow simplifcations during match rather than just during reassoc/ifcombine.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
gcc/ChangeLog:
PR tree-optimization/106164
* match.pd (`a != b & a <= b`, `a != b & a >= b`,
`a == b | a < b`, `a == b | a > b`): Handle these cases
too.
gcc/testsuite/ChangeLog:
PR tree-optimization/106164
* gcc.dg/tree-ssa/cmpbit-2.c: New test.
