We were looking at the unreachable flag or stack_depth of the target frame instead of the current one in a couple of places (most notably BreakTo). This change fixes these bugs and makes us pass the latest spec tests for br_table validation. Also need to ensure that br_table targets have consistent types, which is not implied if the stack is polymorphic.
