aco/optimizer_postRA: Use unique_ptr + array for instruction indices.
According to perf, this roughly halves the impact of the post-RA
optimizer in ACO's compile times.
Measurement was taken using a debug optimized build using
NIR_DEBUG=novalidate RADV_DEBUG=nocache and replaying the Fossil DB
from the Doom Eternal shaders.
