Should //run-rustfix tests apply HasPlaceholders suggestions?

[Manishearth]

Applying // run-rustfix to tests/ui/float_cmp_const.rs causes the HasPlaceholders suggestions contained within that lint to be applied.

Do we actually want this behavior? HasPlaceholders suggestions are things that should be applied manually imo.

// run-rustfix seems to apply even MaybeIncorrect ones, unless there is rustfix-only-machine-applicable directive. 😞

[flip1995]

There is // rustfix-only-machine-applicable, which we could add to those lints. If we run cargo fix --clippy only the MachineApplicable lints get applied? In that case we could run rustfix tests only for MachineApplicable lints.

Maybe we should invert those? But that sounds annoying too, maybe we should just close this.
