[Mesa-dev] gallivm: integer opcode preparation

[Dave Airlie]

Hi guys,

These 5 patches are the basis for adding integer opcodes to gallivm.

They deal with the fetch and store paths, so that the code can
infer from the instruction, what sort of data to give to the processing
and what sort of data to store from it.

These patches shouldn't do anything since we don't support any
of the opcodes yet while integers are disabled.

I'd just like to merge this piece by piece and this is most of the
pieces that really interact with the code Tom was working on.

Dave.
