Review comment:
Actually I'm a bit confused by the original semantic. It meant to
overwrite the name with var's name if var is an IterVar, but not to overwrite
if var is a VirtualAxis which already has a name. Plus, when name=None and var
is an IterVar, name_ct increments by 1 but it's not used in naming. Is this
what it is supposed to be?
