[PATCH] D134433: [AMDGPU][GISel] Enable Matching of V2S16 G_BUILD_VECTOR

[Petar Avramovic via Phabricator via llvm-commits]

Does D134354 <https://reviews.llvm.org/D134354> work for non vector cases?
My best guess is that it does not work for vectors of two elements where it would need to create two instructions (missing some build vector combine/legalizer rule). You would expect that all those build vectors in between are gone after legalizer?
