* Redesign 64-bit HEAP_ALLOCED (FIX #2934 at the same time)
Ignore-this: 4018145c528e52995d1feb7636e34384
After much experimentation, I've found a formulation for HEAP_ALLOCED
that (a) improves performance, and (b) doesn't have any race
conditions when used concurrently. GC performance on x86_64 should be
improved slightly. See extensive comments in MBlock.h for the
details.
