17c8fefc9f R600/SI: Do abs/neg folding with ComplexPatterns 
Abs/neg folding has moved out of foldOperands and into the instruction
selection phase using complex patterns.  As a consequence of this
change, we now prefer to select the 64-bit encoding for most
instructions and the modifier operands have been dropped from
integer VOP3 instructions.

635fb9fb59 R600/SI: Fold immediates when shrinking instructions 
This will prevent us from using extra MOV instructions once we prefer
selecting 64-bit instructions.

e5fc4208eb R600/SI: Fix incorrect commute operation in shrink instructions pass 
We were commuting the instruction by still shrinking it using the
original opcode.

NOTE: This is a candidate for the 3.5 branch.
