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

compiler.cfg.*: detached the normalize-height and schedule-instructions passes
...
those stages cause uninitialized "holes" in the stacks which in turn
causes gc errors if stack underflows occur

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.
