[PATCH] D45921: Add getDeserializationListener to ASTReader

[Yuka Takahashi via Phabricator via cfe-commits]

yamaguchi created this revision.
yamaguchi added reviewers: v.g.vassilev, rsmith, dblaikie, thakis.

We need to know if ASTReader already has a DeserializationListner or
not, and this also helps to create a multiplexing deserialization
listener if there is one already attached.
