Looking up methods is awkward

[dmlloyd]

It would be nice to improve method lookup. Right now, this is what is necessary to find the standard main method:

        DefinedTypeDefinition stringClass = bcc.findDefinedType("java/lang/String");
        if (stringClass == null) {
            context.error("String class not found (missing JDK?)");
            return delegate;
        }
        TypeSystem ts = context.getTypeSystem();
        LiteralFactory lf = context.getLiteralFactory();
        ReferenceType stringArray = ts.getReferenceType(lf.literalOfArrayType(ts.getReferenceType(stringClass.validate().getTypeId())));
        int idx = userMainClass.validate().resolve().findMethodIndex("main", MethodDescriptor.of(ParameterizedExecutableDescriptor.of(stringArray), ts.getVoidType()));
        if (idx == -1) {
            context.error("No main method found on main class %s", mainClassName);
            return delegate; // bail out
        }
        final MethodElement userMain = userMainClass.validate().getMethod(idx);

(edited because it's actually even worse)

This is largely improved now.
