7002a9ee83 Fix false positive with cast_sign_loss lint
`cast_sign_loss` lint incorrectly suggests that the result of
`checked_abs`, `rem_euclid` and `checked_rem_euclid` cannot
be casted to an unsigned integer without loss.

Split up cast.rs tests, run-rustfix for unnecessary_cast
This splits up the cast.rs tests and enables rustfix tests for the part
of the `unnecessary_cast` lint that emits `MachineApplicable`
suggestions.

3cf8c0b3b5 Fix cast_sign_loss false positive
This checks if the value is a non-negative constant before linting about
losing the sign.

Because the `constant` function doesn't handle const functions, we check if
the value is from a call to a `max_value` function directly. A utility method
called `get_def_path` was added to make checking for the function paths
easier.

Fixes #2728
