Issue Description:

Project: https://github.com/Snowy1803/Snowymage-Swift

Target: SNIConverter (Swift Argument Parser command line tool)

Other targets are fine. Building for debug is fine. The compiler crashes when building for release. I am using Swift Concurrency: It is probably caused by that, as it happens in a `runAsyncAndBlock` closure.

The error is:

Assertion failed: (IGM.DebugInfo->verifyCoroutineArgument(Addr) && "arg expected to be load from inside %swift.context"), function visitDebugValueAddrInst, file /Users/buildnode/jenkins/workspace/oss-swift-package-macos/swift/lib/IRGen/IRGenSIL.cpp, line 4368.

The full logs are attached.

We made a lot of improvements in the compiler recently and I can't reproduce this any more using the 03-07 toolchain. Let me know if you can confirm.
