'objc_ownership_cfretain' -> 'cf_ownership_retain'
'objc_ownership_cfrelease' -> 'cf_ownership_release'

Motivation: Core Foundation objects can be used in isolation from Objective-C,
and this forces users to reason about the separate semantics of CF objects. More
Sema support pending.

to add 'CFMakeCollectable' semantics to a method.

'objc_ownership_cfrelease'. These are the 'release' equivalents of
'objc_ownership_retain' and 'objc_ownership_cfretain' respectively.

as 'objc_ownership_cfretain' except that the method acts like a CFRetain instead
of a [... retain] (important in GC modes). Checker support is wired up, but
currently only for Objective-C message expressions (not function calls).

incremented).

Objective-C method or C function increments the reference count of a passed
object.

down to the ActionBase class.  This eliminates dependencies of (e.g.)
DeclSpec.h on Action.h, meaning that action.h can now include these
headers and use their types directly in the actions interfaces.

This is a refactoring to support a future change, no functionality
change.

We don't have "zero cost" exceptions for ObjC yet, so there is no codegen
support required.

1) implement parser and sema support for reading and verifying attribute(warnunusedresult).
2) rename hasLocalSideEffect to isUnusedResultAWarning, inverting the sense
   of its result.
3) extend isUnusedResultAWarning to directly return the loc and range 
   info that should be reported to the user.  Make it substantially more
   precise in some cases than what was previously reported.
4) teach isUnusedResultAWarning about CallExpr to decls that are 
   pure/const/warnunusedresult, fixing a fixme.
5) change warn_attribute_wrong_decl_type to not pass in english strings, instead,
   pass in integers and use %select.

Don't ignore the const attribute - we even have CG support for that. Do ignore the malloc attribute however.
