See https://reviews.llvm.org/D47106 for details. Reviewed By: probinson Differential Revision: https://reviews.llvm.org/D47171 This commit drops that patch's changes to: llvm/test/CodeGen/NVPTX/f16x2-instructions.ll llvm/test/CodeGen/NVPTX/param-load-store.ll For some reason, the dos line endings there prevent me from commiting via the monorepo. A follow-up commit (not via the monorepo) will finish the patch. llvm-svn: 336843
