Justin Holewinski e04e4bdf71 [NVPTX] Calling conventions fix 
Fix ABI handling for function
returning bool -- use st.param.b32 to return the value
and use ld.param.b32 in caller to load the return value.

Justin Holewinski ae556d3ef7 This patch adds a new NVPTX back-end to LLVM which supports code generation for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it. 
The new target machines are:

nvptx (old ptx32) => 32-bit PTX
nvptx64 (old ptx64) => 64-bit PTX

The sources are based on the internal NVIDIA NVPTX back-end, and
contain more functionality than the current PTX back-end currently
provides.
