If a type has no constructors at all, then the compiler automatically generates the
.new
and#initialize
methods. The former is attached to the first declaration of the type, but the latter isn't; this PR gives it the same treatment.In particular,
Reference#initialize
used to have no locations, and this caused the auto-generated constructors for generic classes to lose theirs too:This shows up on Compiler Explorer as the constructors of
Thread::LinkedList(T)
were never considered library code. They are now filtered after this patch.
