Justin Holewinski 43787cd447 PTX: Use .param space for device function return values on SM 2.0+, and attempt 
to fix up parameter passing on SM < 2.0

Justin Holewinski 6cdd72a9ca 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

Che-Liang Chiou 14c48e5d66 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.
