The FIXME was added in 46984 when the diagnostic message looked like this: // FIXME(rust-lang#46983): error message should be better &s.0 //~ ERROR free region `` does not outlive free region `'static` The message was improved in 90667 and now looks like this: &s.0 //~ ERROR lifetime may not live long enough but the FIXME was not removed. The issue 46983 about that diagnostics should be improved has been closed. We can remove the FIXME now.

…compiler-errors Issue numbers are enforced on active features; remove FIXME Since rust-lang#51090 tidy enforces that active features have an issue number, so remove the FIXME. This PR is part of rust-lang#44366 which is E-help-wanted.
