Akira Hatanaka 65bb3f92bd [CodeGen][ObjC] Annotate calls to objc_retainAutoreleasedReturnValue
with notail on x86-64.

On x86-64, the epilogue code inserted before the tail jump blocks the
autoreleased return optimization.

Pete Cooper 2cd3596b1a Generate objc intrinsics instead of runtime calls as the ARC optimizer now works only on intrinsics

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.

John McCall 248512a573 When performing an @throw in ARC, retain + autorelease
the pointer, being sure to do so before running cleanups
associated with that full-expression.  rdar://10042689
