Subject: Change the way we handle temporaries in LLVM translation.

TGSI uses TEMP, among others, as a way of passing arguments
from one function to another. Instead of trying to figure out
which temp's a function needs and trying to dynamically adjust its
signature just pass the whole array of temporaries to them.
