Issue Description:

The following script crashes the compiler in 3.0.2 and latest 3.1:

{ echo 'struct A { let a: String = "" }' > a.swift; echo 'extension A { init(b: String) {} }' > b.swift; swiftc a.swift b.swift }

Perhaps related, a very similar piece of code hangs indefinitely in 3.0.2:

{ echo 'enum A { case a }; struct B { var a: A = .a }' > a.swift; echo 'extension B { init(b: String) {} }' > b.swift; swiftc a.swift b.swift }
