Fixed some inherited record types being incorrectly identified as cla…

There's a problem with the ComputeIsRecord function. It appears to only check whether the current class has functions like ToString, PrintMembers, and GetHashCode.

public abstract Parameter <Clone>$();
public sealed override string ToString();
protected virtual bool PrintMembers(StringBuilder builder);

In reality, as shown above, functions like ToString and PrintMembers are inherited, so as long as the class isn't a base class, these member functions don't need to exist in the current class.

Unfortunately, your solution breaks the laziness of MetdataTypeDefinition by having to materialize all properties and methods when evaluating the IsRecord property. This is not acceptable.
