[PATCH] D77090: AMDGPU/GlobalISel: Change intrinsic ID for _L to _LZ opt

[Sebastian Neubauer via Phabricator via llvm-commits]

Flakebi added a comment.

What is the reason to do this during legalization?
Could we look for a constant zero argument during instruction selection?

Then we could also remove the lz variants of the intrinsics and simply encode this as a constant zero argument.
