Add helper APIs for get_gc implementations
get_gc() implementations that need to explore heterogeneous data
currently work by computing how many GC entries they need,
allocating a buffer for that and storing it on the object. This
is inefficient and wastes memory, because the buffer is retained
after the GC run.
This commit adds an API for a single global GC buffer, which can
be reused by get_gc implementations (as only one get_gc call is
ever active at the same time). The GC buffer will automatically
grow during the GC run and be discarded at the end.
