[Mesa-dev] [PATCH 02/10] i965: Reuse intel_batchbuffer_reset_to_saved() for intel_batchbuffer_free()

[Chris Wilson]

Rather than have a seperate implementation that discards all of the
execobjects for the rare event of destroying the context, recast it as
an operation to reset to the saved state of no batch.
