As we now keep SP at the same place throughout the function body, or only modify
it within the emission for individual pseudo-ops like call, we no longer need
the notion of the nominal-SP. This PR removes all mentions of the nominal SP,
and reworks the docs to more accurately describe the frame layout the backends
currently assume.<!--
