Michael Gottesman f4dfbe94e5 [ownership] Require all operands of ref_tail_addr to have guaranteed ownership. ...

This ensures that the optimizer has a summary of where the ref_tail_addr will no
longer be used. This is important when analyzing the lifetime of the base of the
ref_tail_addr.

I also cleaned up a little the description around the specification for this in
OperandOwnership. Now all instructions that are "INTERIOR_POINTER_PROJECTIONS"
have their own section/macro as a form of self documenting.
