Reland [InstCombine] Teach foldSelectOpOp about samesign (#124320)
Changes: There was a serious bug in the previous patch, leading to a
miscompile. See #122723 for the miscompile report from Alexander, and
the follow-up investigation by Nikita. The patch has since been
reworked, and now includes the testcase from the miscompile.

Follow up on 4a0d53a (PatternMatch: migrate to CmpPredicate) to get rid
of one of the FIXMEs it introduced by replacing a predicate comparison
with CmpPredicate::getMatching.

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
