The ComputeEffects pass derives escape information for function arguments and adds those effects in the function.
This needs a lot of changes in check-lines in the tests, because the effects are printed in SIL

I am going to leave in the infrastructure around this just in case. But there is
no reason to keep this in the tests themselves. I can always just revert this
and I don't think merge conflicts are likely due to previous work I did around
the tooling for this.
In several places, we construct a SubstitutionMap by taking
generic parameters from one SubstitutionMap up to a certain
depth, with the rest coming from a second SubstitutionMap.
Factor this out into a new utility method, to help with
hiding the internal representation of SubstitutionMap from
clients.
This was meant to be NFC, but it actually fixes a crash in
the devirtualizer, because the old logic there was slightly
wrong, so I added a test for this.
