[analyzer] Fix a regression in ObjCUnusedIVars checker.
...
We can no longer rely on children iterator to visit all the AST
tree children of an expression (OpaqueValueExpr has no children).

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>

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.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
