Fix lowering and instruction selection for v3x16 types and enable InstCombine to emit them. This patch only implements it for the selection dag. GlobalISel tests in GlobalISel/llvm.amdgcn.image.load.1d.d16.ll and GlobalISel/llvm.amdgcn.image.store.2d.d16.ll still don't work. Differential Revision: https://reviews.llvm.org/D84420
