[Mesa-dev] [PATCH 3/4] glsl: create a new link_and_validate_uniforms() helper

[Timothy Arceri]

Currently this just breaks up the linking code a bit but in the
future i965 will call this from the backend via Driver.LinkShader()
so that we can do NIR optimisations before assigning uniform
locations.
