introduces global.pendingSuperCall
Similarly to global.emptyValDef, which is a dummy that stands for an
empty self-type, this commit introduces global.pendingSuperCall, which
stands for a yet-to-be-filled-in call to a superclass constructor.
pendingSuperCall is emitted by Parsers.template, treated specially by
Typers.typedParentType and replaced with a real superclass ctor call
by Typers.typedTemplate.
To avoid copy/paste, this commit also factors out and unifies dumminess
of EmptyTree, emptyValDef and pendingSuperCall - they all don't have a
position and actively refuse to gain one, same story for tpe.
