With 828d6fde7f57 (62 fps/79% GPU usage):

With 828d6fde7f57 reverted (79 fps, 100% GPU usage):

Tests were with aco-navi branch:
https://gitlab.freedesktop.org/Venemo/mesa/tree/aco-navi
Performance with LLVM is comparable with the commit reverted or not, however.
Slightly better with the commit since GPU usage is lower for the same
performance:

Mesa aco-navi (e641024) and Mesa git (8dadef2ec54)
