parse.y: Traverse AST post parsing to detect break/next usage issues

Browse source 
Seemed easiest to do it via the traversal infrastructure as we do not
otherwise track enough context/scope when instantiating break or next
statements.

Might be worth moving this out of src/parse.y, but didn't exactly know
where. Or maybe we wait until there's more such trivial validations
popping up

Fixes #2440
