[PATCH] D85473: [Clang] Add option to allow marking pass-by-value args as noalias.

[Florian Hahn via Phabricator via cfe-commits]

fhahn updated this revision to Diff 291083.
fhahn added a comment.

Also restrict to types that are `isNonTrivialToPrimitiveCopy`, so we do not add noalias for problematic types, like ObjC structs with weak references.
