Tom Stellard 36ba7962a4 R600/SI: Fix the FixSGPRLiveRanges pass ...

The previous implementation was extending the live range of SGPRs
by modifying the live intervals directly.  This was causing a lot
of machine verification errors when the machine scheduler was enabled.

The new implementation adds pseudo instructions with implicit uses to
extend the live ranges of SGPRs, which works much better.
