swift-mirror/lib/AST/Builtins.cpp
John McCall 4f6f8b3377 Rewrite hop_to_executor so that it takes a Builtin.Executor in IRGen 
The comment in LowerHopToActor explains the design here.
We want SILGen to emit hops to actors, ignoring executors,
because it's easier to fully optimize in a world where deriving
an executor is a non-trivial operation.  But we also want something
prior to IRGen to lower the executor derivation because there are
useful static optimizations we can do, such as doing the derivation
exactly once on a dominance path and strength-reducing the derivation
(e.g. exploiting static knowledge that an actor is a default actor).

There are probably phase-ordering problems with doing this so late,
but hopefully they're restricted to situations like actors that
share an executor.  We'll want to optimize that eventually, but
in the meantime, this unblocks the executor work.
