BytecodeRecorderImpl should check registered substitutions for both param and expectedType

[starksm64]

Currently the loadObjectInstance(MethodCreator, Object param, Map<Object, ResultHandle>, Class<?> expectedType) method looks for a substitution based on the param.getClass() type. It should also check for a substitution based on the expectedType since that is often what is known. For example, in the jwt fraction, RSAPublicKey interface instances are used for signing, and the underlying implementation can change based on the installed security providers. I have registered a substition for RSAPublicKey since there is no public constructor, but this is not seen as the param type in my jdk is sun.security.rsa.RSAPublicKeyImpl.
