One of the quirks of NIR is that it has allowed SSA references where the
reference uses fewer channels than exist in the SSA value, which surprises
new developers and makes some analysis harder. Jason is about to remove
that quirk and validate that reference num_components == value
num_components, so fix up these passes in preparation.
