3406d882c0 R600/SI: Add more special cases for opcodes to ensureSRegLimit() 
Also factor out the register class lookup to its own function.

58d3335cb9 R600: Move CONST_ADDRESS folding into AMDGPUDAGToDAGISel::Select() 
This increases the number of opportunites we have for folding.  With the
previous implementation we were unable to fold into any instructions
other than the first when multiple instructions were selected from a
single SDNode.

21ca0b3ea4 R600: Use depth first scheduling algorithm 
It should increase PV substitution opportunities and lower gpr
usage (pending computations path are "flushed" sooner)
