[IR] Upgrade comment token in objc retain release marker Older compiler issued '#' instead of ';' llvm-svn: 329248

; Test that comment token for objc retain release is upgraded from '#' to ';'

[ObjC][ARC] Convert the retainRV marker that is passed as a named metadata into a module flag in the auto-upgrader and make the ARC contract pass read the marker as a module flag. This is needed to fix a bug where ARC contract wasn't inserting the retainRV marker when LTO was enabled, which caused objects returned from a function to be auto-released. rdar://problem/49464214 Differential Revision: https://reviews.llvm.org/D60303 llvm-svn: 358047
