        <pre>Clang and MSVC mangle this differently:

  struct B;
  int B::*memptr;

msvc:  ?memptr@@3PQB@@HQ1@
clang: ?memptr@@3PQB@@HA

It looks like it has to do with how we mangle qualifiers.  See the IsMember arg
to mangleQualifiers, which seems to exist for the sole purpose of changing
these codes for member pointers.

Maybe that should only kick in when a memptr type is used in a template or
argument context.</pre>
