[Mesa-dev] RFC: Fine grained caps for shader limits

[José Fonseca]

Attached is my proposal for fine grained caps for shader limits.

These don't cover which opcodes are supported, so PIPE_CAP_GLSL and
PIPE_CAP_SM3 remains. I think that PIPE_CAP_SM3 should be rename to
PIPE_CAP_SM, which shader model major/minor version encoded in a dword.
PIPE_CAP_GLSL could probably be derived from everything else.
