Also introduce USE_ALLOCATION_ALIGNMENT_BOOL constant which is true
only for those configurations that require aligned allocations and
use it for statically falling back to unaligned allocations on those
configurations that do not require aligned allocations.

This is a prerequisite for introducing the real kWordAligned mode for
kSystemPointerSize aligned allocations.
