This came up because I had set RUST_LOG=rustc::middle::typeck::infer=3 in order to debug an unrelated issue in infer, and turning logging on for infer caused this.

the problem here is the synthesized expressions created for predicates in the type check fn check_constraints(). they don't have a real expression id so there is no corresponding entry in the ast_map. this is pretty sketchy code to begin with, so I guess I'd be inclined to change that code rather than the print-out.

on the other hand, that'd be hard. so maybe I'll just make the printouts not fail when they find something unexpected but instead print out a less-than-useful string.

or maybe take the VERY EASY path and remove the preconditions from core::result::iter2

remove FFI support for macOS

We're only testing this on Linux, and `@thomcc` reports that libffi on macOS is a pain, so let's just disable this for now.
