[NVPTX] Use ldg for explicitly invariant loads.
Summary:
With this change (plus some changes to prevent !invariant from being
clobbered within llvm), clang will be able to model the __ldg CUDA
builtin as an invariant load, rather than as a target-specific llvm
intrinsic. This will let the optimizer play with these loads --
specifically, we should be able to vectorize them in the load-store
vectorizer.
