Adds a large sum of TGSI opcodes to the a3xx compiler.

For integer opcodes we have 28 opcodes added.
Adds 4 floating point compare opcodes

If GLSL 1.30 is enabled, this allows the GLSL 1.30 piglits to have a completion amount of 432/641.

Adds the KILL_IF TGSI opcode.
The KILL_IF opcode could potentially be merged in to the regular KILL opcode function.
It was a pain to do so, so I've left is separated for cleanliness.
