Currently, we don't have any intrinsic functions that serve as getter functions. If we add such an intrinsic getter function in the future, we'll need to update DFG::ByteCodeParser::handleIntrinsicCall() to allow for it to be inlined as an intrinsic. Note: this is different from ByteCodeParser::handleIntrinsicGetter() which intrinsify some property gets, and not getter functions.
