Tom Stellard b4a313a76f 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.

Tom Stellard 1bd80725b3 R600/SI: Use VALU instructions for copying i1 values 
We can't use SALU instructions for this since they ignore the EXEC mask
and are always executed.

This fixes several OpenCV tests.
