closes #3692: make instantiateTypeVar more careful so it does not
change T's info to >: T <: T.

closes #3612. relaxed self-type conformance check slightly by
comparing the self types instead of the self-type symbols, which are
trivially different when you introduce a self variable without giving it
a type
given the definitions below (for full context, see test file), before,
O0 would work but O would not, now both are accepted:
{{{
object O0 extends C {}
object O extends C { self => }
}}}
