SI-8046 Only use fast TypeRef#baseTypeSeq with concrete base types
We can only compute the base type sequence (BTS) of a `TypeRef` by
element-wise transforming the BTS of the referenced symbol if
there are no abstract types in its BTS type symbols.
In the now-working test case, `pos/t8046.scala`, the difference
between the old and new calculation of the BTS is:
this = Three.this.Alias[Int]
sym.info.baseTypeSeq = BTS(One.this.Op[A],Any)
mapped BTS = BTS(Three.this.Op[Int],Any)
full BTS = BTS(Three.this.Op[Int],Int => Int,Object,Any)
The change to account for PolyType in ArgsTypeRef#transform is now
needed to avoid the full BTS of:
BTS(Three.this.Op[A],A => A,Object,Any)
Interestingly, everything actually works without that change.
