It checks whether the var type was already remapped.

tree-inline.c:
can_be_nonlocal(...):
  /* We must use global type.  We call remapped_type instead of
     remap_type since we don't want to remap this type here if it
     hasn't been remapped before.  */
  if (TREE_TYPE (decl) != remapped_type (TREE_TYPE (decl), id))
    return false;
