coverage: Treat await similar to a macro

Browse source 
Currently `await` is only counted towards coverage if the containing
function is suspended and resumed at least once. This is because it
expands to code which contains a branch on the discriminant of `Poll`.

By treating it like a branching macro (e.g. `assert!`), these
implementation details will be hidden from the coverage results.
