* Add SpirvTools::IsValid(). Add a method to determine if a SpirvTools object was successfully constructed and can be used. It might not be depending on the parameter to the constructor. This is something a fuzzer wants to know before trying to use an SpirvTools object constructed with a fuzzed parameter.
