[NVPTX] Adding __nvvm_ builtins index

Clang Frontend
#1

Hi Justin,

As we discussed earlier, Clang intrinsics table misses _nvvm buitins, what prevent frontend from recognizing them in the suppiled source code, e.g. nvvm/ci_include.h
The attached patch adds the list of intrinsics. Some of them are commented out, because backend does not implement them yet.

OK to commit?

The patch looks good, but please provide some test cases (see test/CodeGen/ in Clang for examples). It can just be a simple test that makes sure Clang does not error out for these built-ins.
