Performance improvement in
dEQP-VK.ssbo.phys.layout.random.16bit.scalar.13 for n=30:
release build (w/Fedora build flags): -7.79% ± 0.25%
Meson -Dbuildtype=debugoptimized: -5.10% ± 0.40%
The difference in the debugoptimized build is the calls to
inst_is_in_block(block, this) still exist on each call to remove().
v2: Only update each block's IP data once instead of once per block.
