[PATCH] D26057: [coroutines] Add DependentCoawaitExpr and fix re-building CoroutineBodyStmt.

[Eric Fiselier via cfe-commits]

EricWF updated this revision to Diff 76953.
EricWF added a comment.

- Address review comments about `DependentCoawaitExpr` and using `UnresolvedLookupExpr`.
- Fix building of the initial/final coroutine suspends points.
- Fix transformation of `CoroutineBodyStmt` so that it transforms the final/initial suspend points instead of rebuilding them fully.

@rsmith: This change is a little big, but it's not trivial for me to split it up. Please let me know if you would prefer this submitted as multiple patches.
