Justin Holewinski 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
