Doug Gregor d6deeccc81 [Strict memory safety] Fix "unsafe" checking for the for..in loop ...

The `$generator` variable we create for the async for..in loop is
`nonisolated(unsafe)`, so ensure that we generate an `unsafe`
expression when we use it. This uncovered some inconsistencies in how
we do `unsafe` checking for for..in loops, so fix those.

Fixes rdar://154775389.
