Justin Holewinski 871ec93909 [NVPTX] Fix bug in stack code generation causes by MC conversion
We do use a very small set of physical registers, so account for
them in the virtual register encoding between MachineInstr and MC

Justin Holewinski cd069e6dec [NVPTX] Use approximate FP ops when unsafe-fp-math is used, and append
.ftz to instructions if the nvptx-f32ftz attribute is set to "true"

Justin Holewinski 8df08c73c6 [NVPTX] Select -1 instead of 1 when anyextend'ing i1 types
This makes it more consistent with the ZeroOrNegativeOneBooleanContent flag

Justin Holewinski dc5e3b68f5 [NVPTX] Clean up comparison/select/convert patterns and factor out PTX instructions from their patterns
Test case is no breakage

Justin Holewinski f8f7091722 [NVPTX] Remove i8 register class. PTX support for i8 (.b8, .u8, .s8) is rather poor and we're better off just ignoring it and letting LLVM expand all i8 ops out to i16.

Justin Holewinski be8dc6499a [NVPTX] Disable vector registers
Vectors were being manually scalarized by the backend.  Instead,
let the target-independent code do all of the work.  The manual
scalarization was from a time before good target-independent support
for scalarization in LLVM. However, this forces us to specially-handle
vector loads and stores, which we can turn into PTX instructions that
produce/consume multiple operands.

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.
