ir_structure_splitting: New pass to chop structures into their components.

This doesn't do anything if your structure goes through an uninlined
function call or if whole-structure assignment occurs.  As such, the
impact is limited, at least until we do some global copy propagation
to reduce whole-structure assignment.
