GC data structures allocation tracking

Adds a new stl compatible allocator that is used in most GC data
structures. When the data structures allocate and free memory, it
lets the heap know of how much memory was allocated or freed. Using
this info, we dump the approximated stl data structures memory usage
when a sigquit occurs.

The allocation tracking can be disabled with a compile time boolean
flag to remove performance impact.
