DECL_IGNORED_P means it is ignored completely for debug info purposes.
For the ones touched by this patch, we must not do this, we really need to
emit the DIEs as they are referenced from other places, we need to track
their location (DECL_IGNORED_P decls aren't tracked at all e.g. by
var-tracking), etc.
We want to emit them as DW_AT_artificial without DW_AT_name, as the name
is made up.
