Fix extent_alloc_cache[_locked]() to support decommitted allocation. Fix extent_alloc_cache[_locked]() to support decommitted allocation, and use this ability in arena_stash_dirty(), so that decommitted extents are not needlessly committed during purging. In practice this does not happen on any currently supported systems, because both extent merging and decommit must be implemented; all supported systems implement one xor the other.
