Pre-fault mmapped buffers for hash tables.
...
Mmaped pages are copy-on-write references to the zero page, and are
faulted in on the first write. Hash table resize touches most of the
newly allocated buffer, so it's faster to pre-fault all pages after
allocation, instead of having the resize loop interrupted by page
faults.

Disable copy and move for AllocatorWithStackMemory.
...
Since this allocator uses its own buffer field for small allocations,
moving or copying it is ill-defined, because someone might already
use the pointers to its body.
