Updated patch
Ok, trying to call cleanup_tree_cfg() was a never ending cascade of failures,
so I'm giving up on that. This patch instead catches the special case in
expand_case() which we have 1 case statement and instead calls expand_goto()
with that case statement's label. Much smaller patch which fixes the ICE and
seems to be making much better progress on bootstrapping.
