Benjamin Kramer a7c40ef022 Canonicalize header guards into a common format. 
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

Justin Holewinski 9a2350e459 [NVPTX] Add more surface/texture intrinsics, including CUDA unified texture fetch 
This also uses TSFlags to mark machine instructions that are surface/texture
accesses, as well as the vector width for surface operations.  This is used
to simplify some of the switch statements that need to detect surface/texture
instructions

Justin Holewinski 5959695a16 [NVPTX] Add query support for read-write images and managed variables 
This also fixes a bug in the annotation cache where the cache will not be cleared between modules if multiple modules are compiled in the same process.

Justin Holewinski 0497ab142d [NVPTX] Run clang-format on all NVPTX sources. 
Hopefully this resolves any outstanding style issues and gives us
an automated way of ensuring we conform to the style guidelines.

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.
