R600/SI: Do abs/neg folding with ComplexPatterns

Browse Source 
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.
