From: Timothy Arceri <timothy.arceri at collabora.com>
This will allow us to skip certain things when falling back to
a full recompile on a cache miss such as avoiding reinitialising
uniforms.
In this chage we use it to avoid reading the program metadata
from the cache and skipping linking during a fallback.
