8af78c9cf8 PTX: Fix various codegen issues
- Emit mad instead of mad.rn for shader model 1.0
- Emit explicit mov.u32 instructions for reading global variables
- (most PTX instructions cannot take global variable immediates)

fd8978b021 Extend initial support for primitive types in PTX backend
- Allow i16, i32, i64, float, and double types, using the native .u16,
  .u32, .u64, .f32, and .f64 PTX types.
- Allow loading/storing of all primitive types.
- Allow primitive types to be passed as parameters.
- Allow selection of PTX Version and Shader Model as sub-target attributes.
- Merge integer/floating-point test cases for load/store.
- Use .u32 instead of .s32 to conform to output from NVidia nvcc compiler.

f71720231f Add preliminary support for .f32 in the PTX backend.
- Add appropriate TableGen patterns for fadd, fsub, fmul.
- Add .f32 as the PTX type for the LLVM float type.
- Allow parameters, return values, and global variable declarations
  to accept the float type.
- Add appropriate test cases.

1440e8b918 Inside the calling convention logic LocVT is always a simple
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.
