SI-5731 a few fixes for value classes
I've faced two gotchas.
First of all posterasure, which is supposed to erase ErasedValueType types,
didn't look into ConstantType.value that is known to be smuggling types
(hi Paul that's a plus one).
Secondly ClassManifest.classType[T] assumed that its T is bound by AnyRef,
which is not the case for value types. Here I had two choices:
a) introduce a special method for manifests of value types,
b) remove the upper bound of the type parameter and call it a day.
Since manifests are already deprecated and there's no difference which
method was used to create which manifest, I went for option b).
