[CUDA] Make printf work.
Summary:
The code in CGCUDACall is largely based on a patch written by Eli
Bendersky:
http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20140324/210218.html
That patch implemented an LLVM pass lowering printf to vprintf; this
one does something similar, but in Clang codegen.
