David Blaikie 99f910f179 Correctly model NRVO returns (#7865) ...

The AST doesn't really matter here, since it's NRVO, there's no actual
code to generate to return the value. But having a correct AST does
address at least one clang false-positive diagnostic:
```
error: stack memory associated with local variable 'return_storage' is returned
    3 | fn F() -> bool {
      |           ^
```
