At -O0, prefer objc_storeStrong with a null new value to the2012-10-17T02:28:37+00:00John McCallrjmccall@apple.com2012-10-17T02:28:37+00:00urn:sha1:e68b8f4dcc2b3a6ab03326ad4167f1164cae61e4
combination of a load+objc_release; this is generally better
for tools that try to track why values are retained and
released. Also use objc_storeStrong when copying a block
(again, only at -O0), which requires us to do a preliminary
store of null in order to compensate for objc_storeStrong's
assign semantics.

Make -fobjc-nonfragile-abi the -cc1 default, since it's the2011-10-02T01:16:38+00:00John McCallrjmccall@apple.com2011-10-02T01:16:38+00:00urn:sha1:9b0a7cea0f5bb2d3197ff33734cc5411ea793e10
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.

Change the driver's logic about Objective-C runtimes: abstract out a2011-07-06T00:26:06+00:00John McCallrjmccall@apple.com2011-07-06T00:26:06+00:00urn:sha1:24fc0decfe337258a3dacc7936a9da84e2406cdc
structure to hold inferred information, then propagate each invididual
bit down to -cc1. Separate the bits of "supports weak" and "has a native
ARC runtime"; make the latter a CodeGenOption.
The tool chain is still driving this decision, because it's the place that
has the required deployment target information on Darwin, but at least it's
better-factored now.

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.
