gallium: Refactor the instruction predicate TGSI token.

Browse Source 
Rename it to tgsi_instruction_predicate -- it's no longer an extended
token. Its presence is indicated by a new flag in tgsi_instruction that
indicates whether an instruction is predicated.

Also, change predicate index representation to match the other
tokens that specify register indices.
