Issue Description:

When building my project (repro at https://github.com/MrLotU/bug-repros/tree/ExpectedAClassHere), everything works fine on MacOS but I get a bunch of errors on Linux (docker swift:latest).

Error:

swift: /home/buildnode/jenkins/workspace/oss-swift-5.0-package-linux-ubuntu-18_04/swift/lib/AST/Type.cpp:3096: swift::Type swift::TypeBase::getSuperclassForDecl(const swift::ClassDecl *, bool): Assertion `isa<ClassDecl>(nominalDecl) && "expected a class here"' failed.

$ docker run -ti swift:latest
# swift --version
Swift version 5.0.2 (swift-5.0.2-RELEASE)
# apt update && apt install libssl-dev zlib1g-dev
# git clone --branch ExpectedAClassHere https://github.com/MrLotU/bug-repros && cd bug-repros
# swift build

Full output from build attached, key excerpts:

Also confirmed it fails to repro on macOS (Apple Swift version 5.1 (swiftlang-1100.0.270.6 clang-1100.0.32.1)).

That is from 5.0, so it's possible it's been fixed in 5.1.

Comment by Jari Koopman (JIRA)

I will give it a shot on a Swift 5.1 Docker image too to check if that's the case.

Requires OpenSSL / LibreSSL if building on Mac, so I can't verify that at the moment.
