Revert `Vec::spare_capacity_mut` impl to prevent pointers invalidation The implementation was changed in #79015. Later it was [pointed out](https://github.com/rust-lang/rust/issues/81944#issuecomment-782849785) that the implementation invalidates pointers to the buffer (initialized elements) by creating a unique reference to the buffer. This PR reverts the implementation. r? ```@RalfJung``` |
