[PATCH] D157118: [NFC][Clang] Fix static analyzer concerns

[Elizabeth Andrews via Phabricator via cfe-commits]

eandrews updated this revision to Diff 554063.
eandrews added a comment.

Changed a dyn_cast to cast and handled ObjCAtFinallyStmt similar to how ObjCAtTryStmt is handled, i.e. just check that it exists before calling PrintRawCompoundStmt
