Michael Anthony Knyszek d8997c8c1f runtime: use wb flag instead of gcphase for allocate-black check 
This is an allocator microoptimization. There's no reason to check
gcphase in general, since it's mostly for debugging anyway.
writeBarrier.enabled is set in all the same cases here, and we force one
fewer cache line (probably) to be touched during malloc.

Conceptually, it also makes a bit more sense. The allocate-black policy
is partly informed by the write barrier design.
