Fix race with Heap::ClampGrowthLimit and GC

Aded logic for handling the temp bitmap if the GC is running and
the live bitmap is clamped to the mark bitmap. This fixes the SIGABRT
from ClampGrowthLimit if the GC clamped the bitmaps at this point.

Also added locking of the heap_bitmap_lock_ so that added a lock so
that the temp bitmap doesn't change from underneath us.
