cmd/compile: represent escape analysis callees as a slice

Change the callee variable in escape analysis from a single fn *ir.Name
to a slice fns []*ir.Name, in prep for a follow-up CL that starts
resolving multiple callees.

I replaced the mutable argumentParam func with some plain loops; it was
getting unweildy to manage this state and the final result feels a lot
more understandable (when read without a diff viewer anyway).

No behavior change: fns still contains at most one element.
