Summary: This diff increases autoreleasepool size when * caller is non-ARC-compiled * callee is ARC-compiled * return type is a pointer to objc object To distinguish non-ARC-/ARC-compiled: * extended `translation_unit_decl_info` to have a boolean field `is_objc_arc_on` * then copied it to `ProcAttributes.t` for each procedures.
