    <thetext>Fix use-after-move in Inspector::InspectorDebuggerAgent::didCreateNativeExecutable() in Source/JavaScriptCore/inspector/agents/InspectorDebuggerAgent.cpp.

There are two places where `oldJITCodeRef` is used after being moved in a RELEASE_ASSERT() statement.

```
        [...]
        switch (kind) {
        case JSC::CodeForCall:
            ASSERT(!replacedThunk-&gt;callThunk);
            replacedThunk-&gt;callThunk = WTFMove(oldJITCodeRef);

            ASSERT(!replacedThunk-&gt;callArityThunk);
            replacedThunk-&gt;callArityThunk = WTFMove(oldArityJITCodeRef);

            RELEASE_ASSERT(oldJITCodeRef.code() == createJITCodeRef(vm.jitStubs-&gt;ctiNativeCall(vm)).code());  // Use-after-move of `oldJITCodeRef`.
            break;

        case JSC::CodeForConstruct:
            ASSERT(!replacedThunk-&gt;constructThunk);
            replacedThunk-&gt;constructThunk = WTFMove(oldJITCodeRef);

            ASSERT(!replacedThunk-&gt;constructArityThunk);
            replacedThunk-&gt;constructArityThunk = WTFMove(oldArityJITCodeRef);

            RELEASE_ASSERT(oldJITCodeRef.code() == createJITCodeRef(vm.jitStubs-&gt;ctiNativeConstruct(vm)).code());  // Use-after-move of `oldJITCodeRef`.
            break;
        }
        [...]
