Tree transformer that duplicates code and at the same time creates fresh symbols for existing labels.
Is current phase cancelled on this unit?
If the selector type has a member with the right name, it is the host class; otherwise the symbol's owner.
Generate coercion denoted by "code"

left-hand side of the '=='
right-hand side of the '=='

Returns a list of trees that each should be concatenated, from left to right.
Does this tree have a try-catch block?
If the block consists of a single unconditional jump, prune it by replacing the instructions in the predecessor to jump directly to the JUMP target of the block.
