libclang: add clang_Cursor_getCXXManglings

This function permits the mangling of a C++ 'structor.  Depending on the ABI and
the declaration, the declaration may contain more than one associated symbol for
a given declaration.  This allows the consumer to retrieve all of the associated
symbols for the declaration the cursor points to.
