[Mesa-dev] [PATCH v2 02/10] nir: add new partially_unrolled bool to nir_loop

[Timothy Arceri]

In order to stop continuously partially unrolling the same loop
we add the bool partially_unrolled to nir_loop, we add it here
rather than in nir_loop_info because nir_loop_info is only set
via loop analysis and is intended to be cleared before each
analysis. Also nir_loop_info is never cloned.
