Jordan Rose a34d04d35e Suggest objc_method_family(none) for a property named -newFoo or similar.
As mentioned in the previous commit, if a property (declared with @property)
has a name that matches a special Objective-C method family, the getter picks
up that family despite being declared by the property. The most correct way
to solve this problem is to add the 'objc_method_family' attribute to the
getter with an argument of 'none', which unfortunately requires an explicit
declaration of the getter.

This commit adds a note to the existing error (ARC) or warning (MRR) for
such a poorly-named property that suggests the solution; if there's already
a declaration of the getter, it even includes a fix-it.

Fariborz Jahanian 65b1377911 ObjectiveC. 1) Warn when @dynamic (as well as synthesize)
property has the naming convention that implies 'ownership'.
2) improve on diagnostic and make it property specific.
3) fix the line number in the case of default property
synthesis. // rdar://15757510

Douglas Gregor 0ad84b46e3 Undo my re-wording of the "ARC forbids Objective-C objects in ..."
error. Jordan is right.

Fariborz Jahanian 272b7dc8ae objective-C arc: ns_returns_retained is a type attribute in ARC,
and when used in property type declaration, is handled as type
attribute. Do not issue the warning when declaraing the property.

Patrick Beard acfbe9e1f2 Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared.
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>

John McCall 18a962bab5 Don't suppress access-control or invalid-type diagnostics from a
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.

John McCall 9b0a7cea0f Make -fobjc-nonfragile-abi the -cc1 default, since it's the
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.

Fariborz Jahanian ac8dbf0fc7 objcetive-c-arc: When overriding a method, its ns_consumed patameter
attribute must match its overriden method. Same also for
ns_returns_retained/not_retained on the result type.

John McCall 31168b077c Automatic Reference Counting.
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.
