Justin Holewinski 0984dcc077 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)

Che-Liang Chiou 59515dc703 Add 64-bit addressing to PTX backend
- Add '64bit' sub-target option.
- Select 32-bit/64-bit loads/stores based on '64bit' option.
- Fix function parameter order.

Che-Liang Chiou 65b1476031 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.

Che-Liang Chiou 75a800d3bf 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.

Chris Lattner 66031ed839 move all the target's asmprinters into the main target. The piece
that should be split out is the InstPrinter (if a target is mc'ized).
This change makes all the targets be consistent.
