2c2eb12d9c White-listing templated-scope friend decls is a good idea, but doing it
by marking the decl invalid isn't.  Make some steps towards supporting these
and then hastily shut them down at the last second by marking them as
unsupported.

8fb9512966 Move the maintenance of CXXRecordDecl::DefinitionData's Abstract bit
completely into CXXRecordDecl, by adding a new completeDefinition()
function. This required a little reshuffling of the final-overrider
checking code, since the "abstract" calculation in the presence of
abstract base classes needs to occur in
CXXRecordDecl::completeDefinition() but we don't want to compute final
overriders more than one in the common case.

9d5938ae8a Centralize the management of CXXRecordDecl::DefinitionData's Empty bit
in CXXRecordDecl itself. Yes, this is also part of <rdar://problem/8459981>.

This reinstates r114924, with one crucial bug fix: we were ignoring
the implicit fields created by anonymous structs/unions when updating
the bits in CXXRecordDecl, which means that a class/struct containing
only an anonymous class/struct would be considered "empty". Hilarity
follows.

009f69979a When dealing with an anonymous enumeration declared in function
prototype scope, temporarily set the context of the enumeration
declaration to the translation unit. We do the same thing for
parameters, until we have an actual function declaration on which to
hang them. Fixes <rdar://problem/8435682>.

There is more work to do in this area, since we have existing bugs
with tags being declared/defined in function parameter lists. This fix
is correct, and we'll end up extending it when we deal with those
existing bugs.
