  -----------
  Introduce compile-time checking and alternate allocation for compact pointer types
https://bugs.webkit.org/show_bug.cgi?id=266080
rdar://119382681

Reviewed by Mark Lam.

Adds compile-time checking to WTF compact and packed pointer types requiring the
pointed-to types to be explicitly marked as compatible with compact pointers. Also
adds new equivalents to the existing WTF::fastMalloc and WTF::isoMalloc allocation
functions for compactible types, giving us an API point to play with how types
used in compact pointers are allocated.
