• SR-6333 AsyncNinja source breakage: Assertion failed: (t->is() || t->isExistentialType() && "expected a class, archetype or existential"), function getSuperclassForDecl, file swift/lib/AST/Type.cpp, line 3341.

Issue Description:

$ swift-LOCAL-2017-10-25-a.xctoolchain.base2/usr/bin/swiftc -v
Apple Swift version 4.1-dev (LLVM a2bdb45198, Clang bb20a94e86, Swift ec19cad)
Target: x86_64-apple-darwin17.2.0

(swift/utils/build-toolchain swift build)

source-compat-suite: 112421c (HEAD -> master, origin/master, origin/HEAD) Merge pull request #96 from graydon/misc-run_cperf-fixes

./runner.py --swift-branch master --projects projects.json --swift-version 3 --include-actions 'action.startswith("Build")' --swiftc .../usr
/bin/swiftc

I think we don't see the failure on the bot because the bot builds without assertions.
