When applying ARC __weak to a non-objc pointer, do not give error that
...
__weak is unsupported by the deployment target, since it is going to be
ignored anyway.
Makes it easier for incremental migration from GC.

Introduce a placeholder type for "pseudo object"

expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.
Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

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.

Add an ns_bridged attribute, used to specify that a
...
pointer to the annotated struct type can be used as an
Objective-C object pointer. If an argument is given, the
type is actually "toll-free bridged" to the specific type
named there, rather than just to 'id'.
For now, we cannot rely on all types being so annotated,
and we'll always have to have exceptions for things like
CFTypeRef (aka const void*), but this is clearly a good
foundation for improving toolage in this area.
