2) improve on diagnostic and make it property specific.
3) fix the line number in the case of default property
synthesis. // rdar://15757510

and when used in property type declaration, is handled as type
attribute. Do not issue the warning when declaraing the property.

The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

declarator just because we were able to build an invalid decl
for it. The invalid-type diagnostics, in particular, are still useful
to know, and may indicate something about why the decl is invalid.
Also, recover from an illegal pointer/reference-to-unqualified-retainable
type using __strong instead of __autoreleasing; in general, a random
object is much more likely to be __strong, so this avoids unnecessary
cascading errors in the most common case.

increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.
This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.
Most, though, it involved a perl script to translate a ton
of test cases.
Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

ns_returns_retained/not_retained on the result type.

Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.
Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.
