util/ra: Improve ra_set_finalize() performance. BITSET_FOR_EACH_SET can walk a sparse set (such as a register class's set of registers) much faster than just iterating over individual bits. Improves freedreno startup time (as measured by shader-db ./run shaders/closed/gputest/triangle on my x86 system) by -4.12679% +/- 1.99006% (n=151) Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/4537>
