[PATCH] D138186: InstCombine: Simplify vector load based on demanded elements

[Piotr Sobczak via Phabricator via llvm-commits]

piotr added a comment.

I've always thought we didn't have such a transformation in the generic instcombine, because it may hurt some targets, but I don't immediately see how. (We do have a similar one for intrinsic loads in the AMDGPU-specific file).
