John McCall 63f844494d ARC writeback isn't supposed to apply to local indirect pointers,
only to pointers to locals.  But it should work inside blocks, too.

Fariborz Jahanian f4105f5cfe objc-arc/mrc: Allow ns_returns_not_retained attribute on properties
to turn off warning on those properties which follow Cocoa naming
convention for retaining objects and yet they were not meant for
such purposes. Also, perform consistancy checking for declared
getters of such methods. // rdar://9636091

John McCall d463132f27 Objective-C fast enumeration loop variables are not retained in ARC, but
they should still be officially __strong for the purposes of errors, 
block capture, etc.  Make a new bit on variables, isARCPseudoStrong(),
and set this for 'self' and these enumeration-loop variables.  Change
the code that was looking for the old patterns to look for this bit,
and change IR generation to find this bit and treat the resulting         
variable as __unsafe_unretained for the purposes of init/destroy in
the two places it can come up.

John McCall 31168b077c Automatic Reference Counting.
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.
