Why using 'new' is allowed in pure functions but calling
GC.addRange or GC.removeRange isn't allowed?
Is it valid if I call GC.addRange with same or overlaping range?

It look like that dub compile with ldc but use dmd runtime and
module core.internal.atomic has version only for dmd and gdc. How
to make ldc use ldc runtime?
