munge_id

A label declaration looks like: ".label $LABEL:", from which a normal PIR label is created, formatted as: "_unique_MACRO_LABEL_?:".

A label expansion looks like ".$LABEL", from which a label identifier is generated, formatted as: "_unique_MACRO_LABEL_?" (note the difference, there is no colon at the end.

The same works for local identifiers, but of course the is_label_declaration argument must be 0 for that.
