From: Dave Airlie <airl...@redhat.com>
This writes the subroutine indicies to the program storage for
a stage. This API is intended to be used by drivers to update
the uniform storage before uploading to the hw.
This isn't the most thread safe effort, but it will be significantly
more multi-context safe.
