Merge return assumes that the only unreachable blocks are those needed to keep the structured cfg valid. Even those must be essentially empty blocks. If this is not the case, we get unpredictable behaviour. This commit add a check in merge return, and emits an error if it is not the case. Added a pass of dead branch elimination before merge return in both the performance and size passes. It is a precondition of merge return. Fixes #1962.
