remove InPlaceIterable marker from Peekable due to unsoundness
...
The unsoundness is not in Peekable per se, it rather is due to the
interaction between Peekable being able to hold an extra item
and vec::IntoIter's clone implementation shortening the allocation.
An alternative solution would be to change IntoIter's clone implementation
to keep enough spare capacity available.

Try to make Vec benchmarks only run code they are benchmarking
...
Many of the Vec benchmarks assert what values should be produced by the
benchmarked code. In some cases, these asserts dominate the runtime of
the benchmarks they are in, causing the benchmarks to understate the
impact of an optimization or regression.

Auto merge of #75974 - SkiFire13:peekmut-opt-sift, r=LukasKalbertodt
...
Avoid useless sift_down when std::collections::binary_heap::PeekMut is never mutably dereferenced
If `deref_mut` is never called then it's not possible for the element to be mutated without internal mutability, meaning there's no need to call `sift_down`.
This could be a little improvement in cases where you want to mutate the biggest element of the heap only if it satisfies a certain predicate that needs only read access to the element.
