Hello,

Profiling my app (PCSX2), it seems a fair amount of time is spend on the
_mesa_sampler_uniforms_pipeline_are_valid. I only uses a single pipeline object
so it always trigger revalidation of the pipeline which isn't ideal.

Anyway, it feels that it ought to be possible to cache/prevalidate sampler of
program like the _mesa_sampler_uniforms_are_valid function (which is the same
function but for monolithic build). 

It would be nice to reduce the overhead of the function. Perf reports around 4%
of nouveau_dri.so.

Thanks,
Gregory
