VM: refactor gc_event so that the phase times are stored in an array
...
So that you don't need a new method for each gc phase to time.

VM: big refactoring removing the gc_workhorse
...
Each collector were a slot_visitor containing a gc_workhorse containing
a policy class. This commit removes the gc_workhorse and the policies
and instead "inlines" the common code in the collector bodies. So there
is more code duplication, but the control flow doesn't "jump around" so
much so it is easier to understand. It also makes the nursery gc faster
because its collection code can be optimized better without the
workhorse/policy system.

VM: removes the collector class
...
The cheneys_algorithm() method can be moved to slot_visitor (because it
kind of visists objects), and then there is no need for the collector
class.

VM: moving collector methods to slot_visitor methods
...
collector::trace_cards moved to slot_visitor::visit_cards and
collector::trace_code_heap_roots moved to
slot_visitor::visit_code_heap_roots. Both those methods are pointer visitors

vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead
