it easier to find bad accesses to shadow data

183ec83a6d
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.

016614747d
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.

Reorganising bootstrap files
...
All the bootstrap.factor scripts in cpu/ are run by the bootstrap to
make boot images, but aren't used otherwise. So I think it's cleaner to
put them in one directory inside the bootstrap hierarchy.

VM: the compiler doesn't emit any live overinitialized locations anymore
...
Any overinitialized location immediately becomes garbage and is not
reused again. This is very nice because then the gc maps can be
simpler again.

VM: instead of passing around the trace_contexts_p arg, just clear the contexts in primitive_save_image_and_exit() it has the same effect but is simpler

4d7bc4c169
VM: merge of slot_visitor and code_block_visitor

Looks like there is no reason for them to be separate classes and by
merging them you can simplify lots of code.
