[Bug c++/35201] New: libdemangle no longer distinguishes constructor/destructor variants

[sanjay3000 at gmail dot com]

The C++ ABI at http://www.codesourcery.com/cxx-abi/abi.html defines:

 <ctor-dtor-name> ::= C1 # complete object constructor
     ::= C2 # base object constructor
     ::= C3 # complete object allocating constructor
     ::= D0 # deleting destructor
     ::= D1 # complete object destructor
     ::= D2 # base object destructor

However, libdemange/c++filt no longer translate those specifiers. I think this
is a regression from previous revisions of the library. They used to specify
"in-charge" or other strings for the various ctor/dtor flavors.

Example of raw constructor string:
_ZN9DagSymbolC2Ev
_ZN9DagSymbolC1Ev

These both are demangled as:
DagSymbol::DagSymbol()

Yes, the old demangler printed additional text in some cases when DMGL_VERBOSE
was passed as a flag.  c++filt passes that flag.  The new demangler doesn't
print that additional text.  There are several FIXME comments in
libiberty/cp-demangle.c which marks the places which could or should be
changed.
