Protect/Unprotect regions (region space) only in debug buildlineage-17.0
During performance analysis it was observed that the
allocation-intensive workloads get negatively impacted by the region
protect/unprotect. Therefore, we enable this only on debug builds.
Some of the most affected benchmarks on Golem are as follows:
Benchmark | armv8 | armv7 | x64 | x32
