Submitted by Kristof Szabados

Link to original bug (#500499)
Description
In several places in the parser return value initialization is done incorrectly.
Rules like this " pr_Identifier returns [Identifier identifier = null] "
should be rewritten to " pr_Identifier returns [Identifier identifier] @init{ $identifier = null; } "
