[PATCH] D46760: [InstCombine] Enhance narrowUDivURem.

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

This (walking users of a value) stretches instcombine beyond the simplistic transforms that I think most people want to see here.

Have a look at the BypassSlowDivision (runs within -codegenprepare I think) and DivRemPairs (-div-rem-pairs) passes.
