an_id without the type qualifier used by GccXml to mark the
"const", "reference" and "volatile" qualifier are represented in a
CvQualifiedType node adding 'c', 'r' and 'v' to the identifies. i.e.
if "int" has id "_422" a "const int foo" argument type will be of
type CvQualifiedType with it "_422c". The same rule is used - as far
as I know - also for reference and volatile types.
Result is identical to an_id if it does not end with 'c', 'r' and
'v'; otherwise it is a copy of an_id with the last character ('c',
'r' or 'v') removed.
