[PATCH] D123962: [InstCombine] fold freeze of partial undef/poison vector constants

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Given that we are replacing `freeze constant` with `constant`, and selecting the constant based on all the users,
can we instead go over all the users, and perform replacement for each one separately, always picking the best choice?
