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.

d8149c1bef PTX: Always use registers for return values, but use .param space for device 
parameters if SM >= 2.0

- Update test cases to be more robust against register allocation changes
- Bump up the number of registers to 128 per type
- Include Python script to re-generate register file with any number of
  registers

5efde18dd2 ptx: fix parameter ordering 
This patch depends on the prior fix r129908 that changes to use std::find,
rather than std::binary_search, on unordered array.
