[NVPTX] noop when kernel pointers are already global
Summary:
Some front ends make kernel pointers global already. In that case,
handlePointerParams does nothing.
Test Plan: more tests in lower-kernel-ptr-arg.ll
Reviewers: grosser
Subscribers: jholewinski, llvm-commits
Differential Revision: http://reviews.llvm.org/D10779
llvm-svn: 240849
