Let's not unnecessarily use API handles. We can just have 

    Runtime::DefineObjectProperty(
        builtins,
       
factory()->InternalizeOneByteString(STATIC_CHAR_VECTOR("harmony_regexps")),
        isolate()->heap()->ToBoolean(FLAG_harmony_regexps), NONE).Assert();

I assume you took the code from Genesis::Genesis. There is no internal way to
initialize a typed array, which is why API methods are used there.

Done.

+  Runtime::DefineObjectProperty(builtins,

+                                Utils::OpenHandle(*flag), NONE).Assert();
