[NVPTX] Add preliminary intrinsics and codegen support for textures/surfaces This commit adds intrinsics and codegen support for the surface read/write and texture read instructions that take an explicit sampler parameter. Codegen operates on image handles at the PTX level, but falls back to direct replacement of handles with kernel arguments if image handles are not enabled. Note that image handles are explicitly disabled for all target architectures in this change (to be enabled later). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205907 91177308-0d34-0410-b5e6-96231b3b80d8

[NVPTX] Add more surface/texture intrinsics, including CUDA unified texture fetch This also uses TSFlags to mark machine instructions that are surface/texture accesses, as well as the vector width for surface operations. This is used to simplify some of the switch statements that need to detect surface/texture instructions git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213256 91177308-0d34-0410-b5e6-96231b3b80d8
