Issue Description:

The following command for swift protobuf produces a compiler crash in Swift 5.4-RELEASE: swift test -c release -Xswiftc -enable-testing.

To reproduce, clone swift-protobuf (git clone https://github.com/apple/swift-protobuf) and checkout revision fefa1cdf89e811dfcfa121be86ba4a6a52933f0f. Run the above command line and the crash happens deterministically.

Annoyingly, there isn't much in the way of logging: the output is only error: fatalError. Grabbing a stack from the crashing process I got the following backtrace:
