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.
