IGC v2.20.5

Known issues

In this release we observe 5-10% regressions in the following scenarios specific to the Arrow Lake platform:

Ze_peak_int16,  ARL-S
Ze_peak_int2, ARL_H
Cl_peak_int, ARL_H
Cl_peak_int2, ARL_H

The regression is expected to be contained to benchmarks measuring peak performance.
Real-world scenarios are effectively non-affected.
