[Richard Smith - zygoloid via Phabricator via llvm-commits]

rsmith added a comment.

Hi, I'm seeing a heap-use-after-free in `AggressiveInstCombine` in a build shortly after this landed, within a function added here.

`test/Transforms/AggressiveInstCombine/X86/sqrt.ll` fails as follows under asan: https://gist.github.com/zygoloid/a270e65d32ab5b05504b3b0d5717f83b

Please can you fix or revert?
