R600 Patches (Plus one for SI): Various fixes to get the piglit all_cl tests to stop hanging

[Vincent Lejeune]

I modified your patch adding the isFetch bit, and I have another one that could be used instead of the NOP patch.

With them, I can emit native VTX/TEX clauses which should solve the bug with MaxFetchInst with no regression,
but I still need to work things to have prettier asm output and also fix lit test.
