adds ClassSymbol.baseClasses

Sure this stuff is also declared in Type.baseClasses, but this is
one of the hot paths in reflection (e.g. like ClassSymbol.typeParams),
so I think it's justified to have it as a dedicated method.

Unfortunately we cannot remove Type.baseClasses, because it includes
ridiculously involved calculation of base classes for compound types.
