Fixed minor printing bug.
Fixed typechecker bug where dereferences were ignored when setting
the type of a 'this' expression.
Added file to test bug which was just fixed by last commit.
Fixed bug where typechecking is giving up when this.QT!=that.QT where in
fact it should drop the qualifiers of both sides, since those have been
checked by clang itself.
