acd2be46f1 std::vec: use some unsafe code to optimise remove. 
Also, add `.remove_opt` and replace `.unshift` with `.remove(0)`. The
code size reduction seem to compensate for not having the optimised
special cases.

This makes the included benchmark more than 3 times faster.

81632513c1 std::vec: replace .insert with a small amount of unsafe code. 
This makes the included benchmark more than 3 times faster. Also,
`.unshift(x)` is now faster as `.insert(0, x)` which can reuse the
allocation if necessary.

4c79b22ef2 std::vec: remove .as_imm_buf, replaced by .as_ptr & .len. 
There's no need for the restrictions of a closure with the above methods.

793eb1d38d auto merge of #10996 : huonw/rust/more-vec-raw, r=cmr 
The removal of the aliasing &mut[] and &[] from `shift_opt` also comes with its simplification.

The above also allows the use of `copy_nonoverlapping_memory` in `[].copy_memory` (I did an audit of each use of `.copy_memory` and `std::vec::bytes::copy_memory`, and I believe none of them are called with arguments can ever alias). This changes requires that `unsafe` code using `copy_memory` **needs** to respect the aliasing rules of `&mut[]`.

8a5a5922c6 std::vec: convert .copy_memory to use copy_nonoverlapping_memory. 
It is required that &mut[]s are disjoint from all other &(mut)[]s, so
this assumption is ok.

5c147cc408 std::vec::bytes: remove the reference to overlapping src and dest in 
docs for copy_memory.

&mut [u8] and &[u8] really shouldn't be overlapping at all (part of the
uniqueness/aliasing guarantee of &mut), so no point in encouraging it.

33b6bf4bc1 std::vec: remove aliasing &mut [] and &[] from shift_opt. 
Also, dramatically simplify it with some tasteful raw pointers, rather
than treating everything as a nail with `transmute`.

4f62c969f6 std::vec: move pointless raw::get and unsafe_get functions. 
This can easily be written as `(*v.unsafe_ref(i)).clone()`, or just
`*v.unsafe_ref(i)` for primitive types like `i32` (the common case).

44fc3c6ea8 add MutableVector::mut_split(self, pred) -> DoubleEndedIterator<&mut [T]> 
This method is the mutable version of ImmutableVector::split.  It is
a DoubleEndedIterator, making mut_rsplit irrelevent.  The size_hint
method is not optimal because of #9629.

At the same time, clarify *split* iterator doc.
