[Mesa-dev] [PATCH] nv50/ir: don't consider the main compute function as taking arguments

[Ilia Mirkin]

With OpenCL, kernels can take arguments and return values (?). However
in practice, there is no more TGSI compute implementation, and even if
there were, it would probably have named functions and no explicit main.

This improves RA considerably for compute shaders, since temps are not
kept around as return values.
