Tests failures were caused by previous incomplete implementation of classTag.
Now diagnoses missing ClassTags of abstract types as implicit failures. Also: Simpler API of tpd.clsOf.
If a classtag for `T` is available, a classtag for `Array[T]` can also be generated.
Context bounds did not make it before into secondary constructors. Now the evidence parameters generated by context bounds get copied into secondary constructors. Without this fix, scala.collection.immutable.PagedSeq fails to compile in new classtag scheme.
Make use of Definitions as the repository for standard symbols in Predef.
Now subsumed by functionality in Typer.

Closed as a separate PR. #1111 contains all commits of this PR anyway, and I did not want to have to do the busywork of rebasing each PR separately. |
