996049d45c81f55a4bf4e98cb741621d8876a586 [scudo][standalone] Skip irrelevant regions during release
With the 'new' way of releasing on 32-bit, we iterate through all the
regions in between `First` and `Last`, which covers regions that do not
belong to the class size we are working with. This is effectively wasted
cycles.
With this change, we add a `SkipRegion` lambda to `releaseFreeMemoryToOS`
that will allow the release function to know when to skip a region.
For the 64-bit primary, since we are only working with 1 region, we never
skip.
