SI-8258 Revert "SI-7335 Remove special case for import of Predef._

This reverts commit 66904556ef34dc81cbb7c09257b013b3ddb76f78.

Conflicts:
    src/reflect/scala/reflect/internal/TreeInfo.scala

As evidenced by the highlights of the stack trace in Scala IDE,
my assertion in the 66904556e wasn't universally true.

The change was only motivated by removing a special case, not in
order to fix some other problem. So the revert is the most straight
forward course of action for now.

I haven't pinned this down with a test outside of Eclipse, and
given the lateness of the hour wrt 2.11.0, I'll have to submit
without one.
