d8e4ed2686 PTX: MC-ize the PTX back-end (patch 1 of N) 
Lay some groundwork for converting to MC-based asm printer. This is the first
of probably many patches to bring the back-end back up-to-date with all of the
recent MC changes.

f47dfba023 PTX: Use external symbols to keep track of params and locals. This also fixes 
a couple of outstanding issues with frame objects occuring as instruction
operands.

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.
