nv50/ir: rewrite the register allocator as GCRA, with spilling
...
This is more flexible than the linear scan, and we don't need the
separate allocation pass for constrained values anymore.

nv50/ir/tgsi: Infer function inputs/outputs.
...
Edit: Don't do it for the main function of (graphics) shaders,
its inputs and outputs always go through TGSI_FILE_INPUT/OUTPUT.
This prevents all TEMPs from counting as live out and reduces
register pressure.

nv50/ir: Decouple DataArray from the dictionary that maps locations to values.
...
The point is to keep an independent dictionary for each function.
The array that was being used as dictionary has been converted into a
"bimap" for two different reasons: first, because having an almost
empty instance of an array with as many entries as registers there are
in the program, once for every function, would be wasteful, and
second, because we want to be able to map Value pointers back to
locations at some point.
