[PATCH] D114272: [InstCombine] Add two optimizations for mul-and-icmp patterns

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

Of the remaining test diffs:
(1) `mul_mask_pow2_ne0_use1` is a multi-use corner case that was added to confirm that we don't go overboard
(2) `pr51551` and `pr51551_2` are handled with a combination of -bdce and -instcombine: https://godbolt.org/z/xr1e96ceM

Do we still need this patch?
