Issue Description:

Compiling a swift file crashes on an assert.

Snapshot: swift-DEVELOPMENT-SNAPSHOT-2020-10-07-a.xctoolchain
I cannot correlate a source line that causes a crash/assert.

Error: Assertion failed: (isActuallyCanonicalOrNull() && "Forming a CanType out of a non-canonical type!"), function CanType, file /Users/buildnode/jenkins/workspace/oss-swift-package-osx/swift/include/swift/AST/Type.h, line 402.

Here is a backtrace:

1.  Apple Swift version 5.3-dev (LLVM 240312aa7333e90, Swift 15bf0478ad7c47c)
2.  While evaluating request IRGenRequest(IR Generation for file "/Absolutepath/Sourcefile.swift")
3.  While evaluating request ExecuteSILPipelineRequest(Run pipelines { IRGen Preparation } on SIL for SpotifyURI.SpotifyURI)
4.  While running pass #​1018 SILModuleTransform "LoadableByAddress".

Hi! The file that exposes that fails this assert is auto-generated and contains a lot of sensitive data. I tried to quickly identify the critical part of if, without success. I will try to find some time to isolate the issue, but that may take a while.
