--- Comment #3 from Joseph Pecoraro <joepeck at webkit.org> ---
Hmm, the so issue here is the sourceURL/sourceMappingURL do not get added when we skip re-parsing via the CodeCache:

When constructing the executable for `Function(str)` we go through:

    frame #0: JSC::CodeCache::getFunctionExecutableFromGlobalCode
    frame #1: JSC::UnlinkedFunctionExecutable::fromGlobalCode
    frame #2: JSC::FunctionExecutable::fromGlobalCode
    frame #3: JSC::constructFunctionSkippingEvalEnabledCheck
    frame #4: JSC::constructFunction
    frame #5: JSC::constructFunction
    frame #6: JSC::callFunctionConstructor

At which point if we do not have it in the CodeCache we parse it. If we do have this in the code cache, we return the cached unlinked function executable skipping parsing.

By skipping parsing we don't update the SourceProvider with the sourceURL/sourceMappingURL, because we normally do that under JSC::Parser<>::parse.
