compiler.cfg.stacks.*: new attempt at fixing the gc maps bugs
...
the padding vocab is inverted so that instead of trying to track which
locations are live, it tracks those which are dead which is much easier
to get right.

compiler.*: merge of ##inc-r and ##inc-d into one instruction ##inc with a loc slot
...
this is nice because it leads to simpler code and matches how ##peek and ##replace instructions work

compiler.cfg.*: new step in finalization: clear-uninitialized
...
this step is supposed to analyze the cfg, find where there are peeks
that can cause stack underflow, and insert replace-imm instructions so
that there are no uninitialized stack locations if they do. could fix #1187

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.

compiler.cfg.stacks.vacant: compiler pass replacing uninitialized for more accurate stack maps
...
This pass uses a better algorithm for keeping track of all stack
manipulations which means that the stack maps it assigns are much more
precise.
