R600: Add support for SET*_DX10 instructions

These instructions compare two floating point values and return an
integer true (-1) or false (0) value.

When compiling code generated by the Mesa GLSL frontend, the SET*_DX10
instructions save us four instructions for most branch decisions that
use floating-point comparisons.

R600: Consolidate sub register indices.
