Issue Description:

There are three ForcedVerbatimBridge validation-tests in DictionaryTrapsObjC.swift, which crash when compiling with optimizations.

The entire test file was previously disabled, and the three tests will now be disabled with #if DEBUG.

@benrimmington I cannot reproduce this. Did you try with top of main? Any build-script options you used?

I cannot reproduce this.

@@eeckstein Neither can I now. I've created apple/swift#36426 to remove the DEBUG-only restriction.

Did you try with top of main?

I would have used top of main, 3 weeks ago, for apple/swift#36072.

Any build-script options you used?

I would probably have started with
utils/build-script --clean --release-debuginfo --test,
followed by utils/run-test.
