Justin Bogner 2d5de7e568 NVPTX: Use the nvvm builtins to read SRegs rather than the legacy ptx ones
The ptx spellings were removed from LLVM in r274769.

Artem Belevich 4e192df778 [cuda] Added support for CUDA built-in variables.
Added cuda_builtin_vars.h which implements built-in CUDA variables
using __declattr(property).

Fields of built-in variables (except for warpSize) are implemented
using __declattr(property) which replaces read/write of a member field
with a call to a getter/setter member function, in this case with
appropriate NVPTX builtin.

Added a test case to check diagnostics on attempt to construct or
improperly access a built-in variable.

Artem Belevich a050112bba Revert r235398 "[cuda] Added support for CUDA built-in variables."
r235398 was causing buildbot break due to missing Makefile changes.
