VM: possible fix for #1319 .
...
Fix for reset_context() so that the top two stack items are never
removed from the stack so if the parent->init_context(ctx) call triggers
a GC, those items are never collected.

VM: the delete_context() and reset_context() api functions can be
...
simplified a bit
The functions always operates on parent->ctx, so passing a context*
parameter is redundant. This enables shorter assembly code for
the (start-context-and-delete) and (set-context-and-delete) primitives.

cell and void* is always the same size, but now you can remove lots of
redundant type casts from void* to cell.

VM: move the stack scrubbing logic to call_frame_slot_visitor to avoid visiting the callstack twice
...
primitive_minor_gc() iterates the stack twice, first to scrub stack
locations, then to trace overinitialized ones and gc roots. By running
visit_callstack() before visit_stack_elements() you only need to do it
once.

Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.
