d9c382441b 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)

2e7bb6da4c 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.

4026d01040 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.
