MSVC still mangles the tag into the type, making the manglings for class
and struct differ.  We even have code for this in MicrosoftMangle.cpp.  The
consequence is that you have to use the right tag when you forward declare
something, which we can spot with -Wmismatched-tags.  I don't think this is
a very big deal, and we can probably remove the rule.
