  Reland: [InstCombine] Combine and->cmp->sel->or-disjoint into and->mul (#142035)

Reland of https://github.com/llvm/llvm-project/pull/135274

The commit to land the original PR was blamelisted for two types of
failures:

https://lab.llvm.org/buildbot/#/builders/24/builds/8932
https://lab.llvm.org/buildbot/#/builders/198/builds/4844

The second of which seems to be unrelated to the PR and seemingly fixed
by
https://github.com/llvm/llvm-project/commit/6ee2453360e986c1258e83ce854919adf452b990

I've addressed the fix to the other issue with the latest commit in this
PR b24f4731aaeb753c9269dbd9926cc83c7456f98e . This is the only
difference between this PR and the previously accepted PR.
