[PATCH] D30775: [coroutines] Refactor SuspendExpr to create just one OpaqueValue (almost NFC)

[Gor Nishanov via Phabricator via cfe-commits]

Herald added a subscriber: mehdi_amini.

Create only one OpaqueValue for await_ready/await_suspend/await_resume.
Store OpaqueValue used in the CoroutineSuspendExpr node, so that CodeGen does not have to hunt looking for it.
