macOS-enabled tests are failing

[adamlesinski]

Many of the macOS-only tests in tests/expectations are failing. Using rustc 1.58.1. Here is one example:

error[E0310]: the parameter type `ObjectType` may not live long enough
   --> /Users/adamlesinski/workspace/rust-bindgen/tests/expectations/tests/libclang-4/objc_template.rs:63:9

    |                                     ---------- help: consider adding an explicit lifetime bound...: `ObjectType: 'static`
...

    |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ...so that the type `*mut ObjectType` will meet its required lifetime bounds...

   --> /Users/adamlesinski/.cargo/registry/src/github.com-1ecc6299db9ec823/objc-0.2.7/src/message/mod.rs:177:51

    = note: this error originates in the macro `msg_send` (in Nightly builds, run with -Z macro-backtrace for more info)

Thanks for the report. It looks like you found #1954, which has been broken for a while.
