[Mesa-dev] [PATCH V2] mesa/compiler: add stage to shader_info

[Timothy Arceri]

This will allow us to simplify the current program logic for SSO.

Also since we aim to detach shader_info from nir_shader this will come
in handy avoiding passing nir_shader around just to keep track of
the stage we are dealing with.

V2: set stage for arb asm programs also.
