[drow-cplus-branch] Print qualifiers on methods

David Carlton pointed out that when I switched to printing methods by their
type I lost the const/volatile qualifiers for methods.  They're stored as
the type of the THIS pointer in the argument list.  This patch recovers
them; committed just to the branch since the surrounding code is quite
different from the trunk.  I'll move it over when I've finished with my work
on the type printer.
