Rollup merge of #64375 - kornelski:vecdrop, r=rkruppe
Fast path for vec.clear/truncate For trivial types like `u8`, `vec.truncate()`/`vec.clear()` relies on the optimizer to remove the loop. This means more work in debug builds, and more work for the optimizer. Avoiding this busywork is exactly what `mem::needs_drop::<T>()` is for.
