Doug Gregor f8eee50310 [Constraint solver] Fix function builders with single-expression closures ...

Fix a few related issues involving the interaction with
single-expression closures:

* A single-expression closure can have a "return" in it; in such
cases, disable the function-builder transform.
* Have the function builder constraint generator look through the
"return" statement in a single-expression closure the same way as
solution application does

Fixes rdar://problem/59045763, where we rejected some well-formed code
involving a single-expression closure with a "return" keyword.
