Do not promote values with const drop that need to be dropped Changes from #88558 allowed using `~const Drop` in constants by introducing a new `NeedsNonConstDrop` qualif. The new qualif was also used for promotion purposes, and allowed promotion to happen for values that needs to be dropped but which do have a const drop impl. Since for promoted the drop implementation is never executed, this lead to observable change in behaviour. For example: ```rust struct Panic(); impl const Drop for Panic { fn drop(&mut self) { panic!(); } } fn main() { let _ = &Panic(); } ``` Restore the use of `NeedsDrop` qualif during promotion to avoid the issue. 2021-10-16 19:00:00 -05:00			`error[E0716]: temporary value dropped while borrowed`
