Dan Elphick 58761221af [parser] Delete unresolved variables created for labels
This deletes unresolved VariableProxy objects created for labels in the
preparser which prevents shadowed variables in enclosing scopes from
being context-allocated.

Previously this was only done in the full parser, which leads to
bytecode mismatches with lazy source positions.
