Set a special flag in class metadata when an Objective-C class
has ivars that require destruction, but none that require anything
except zero-initialization. This is common in ARC and (when true
throughout a class hierarchy) permits the elimination of an
unnecessary message-send during allocation.

Rename ObjCMethodDecl::isSynthesized to isPropertyAccessor.

This more accurately reflects its use: this flag is set when a method
matches the getter or setter name for a property in the same class,
and does not actually specify whether or not the definition of the method
will be synthesized (either implicitly or explicitly with @synthesize).

This renames the setter and backing field as well, and changes the
(soon-to-be-obsolete?) XML dump format to use 'property_accessor'
instead of 'synthesized'.

Have 'addFnAttr' take the attribute enum value. Then have it build the attribute object and add it appropriately. No functionality change.

opaque layer is responsible for knowing where that specific attribute is stored.
