While trying to handle cases where multiple symbols could be aliased, we
were trying to relate a symbol to its class by trying to find the
class' demangled name as a substring of the symbol's mangled name. This
might lead to errors when the class is in a qualified namespace (due to
C++ mangled names having fully qualified namespaces of the form
<num-letters><namespace>. Having <num-letters> interspersed between namespaces
makes finding the substring inaccurate). Now, we try find the class' demangled
name in the demangled symbol name instead.

To compare vtable in VTS ABI test, add the option -mangled to have
vndk-vtable-dumper print mangled function names. If the option is not
specified, print demangled names.
