enhance the logic for looking through tailcalls to look through transparent casts
...
in multiple-return value scenarios, like what happens on X86-64 when returning
small structs.

enhance getNoopInput to know about vector<->vector bitcasts of legal
...
types, as well as int<->ptr casts. This allows us to tailcall functions
with some trivial casts between the call and return (i.e. because the
return types disagree).
