Regression in 1.26: lower range bound must be less than or equal to upper

[pietroalbini]

The previous version of the chrono-humanize crate fails to compile with the lower range bound must be less than or equal to upper error (see the build log). No error nor warning was present in the 1.25 release.

error[E0030]: lower range bound must be less than or equal to upper
   --> src/humantime.rs:88:13
    |
 88 |             MIN...-1 => Tense::Past,
    |             ^^^ lower bound larger than upper bound

Since MIN is actually std::i64::MIN, the error is wrong and should be fixed.

• chrono-humanize 0.0.10 regressed from stable to beta (build log) cc @imp

cc @oli-obk -- initial git log dive notes that this could be related to miri transition? Not sure.

Jup it's a regression. Minimal repro:

    const MIN: i8 = -5;
    match 5i8 {
        MIN...-1 => {},
        _ => {},
    }

Not yet fixed on beta, this needs a backport.
