`array::map_8byte_256byte_256` benchmark causes stack overflow

[Sp00ph]

Running python x.py test --stage=0 library/core causes a stack overflow on my machine (64-Bit Windows 11, Build 22621.1105) on the benchmark array::map_8byte_256byte_256 which was recently added in #107915.

If you reduce the size of the benchmarks by 10 (from 25600 elements to 2560), does that still cause stack overflow? I don't think CI reproduces this, and I can't reproduce it since I don't have a machine for it.

Yes, reducing the sizes for map_256byte_8byte_256 and map_8byte_256byte_256 to 2560 fixes the overflow on my machine.
