Fix counters for regions following `else if`s, fix the counters for `else if` conditions, and fix handling of `break` statements. Also while here, clean up the handling of branch exit regions such that we don't generate multiple overlapping regions for each branch, but a single region at the end of the entire `if` statement that accounts for all exiting control flow. rdar://104078910 rdar://104079242
