Switch from indexing to zip, and also use `write` on `MaybeUninit`.

f6411e4c66 Add Array Impl Lang Item in various places
Add basic test

And also run fmt which is where the other changes are from

Fix mut issues

These only appear when running tests, so resolved by adding mut

Swap order of forget

Add pub and rm guard impl

Add explicit type to guard

Add safety note

Change guard type from T to S

It should never have been T, as it guards over [MaybeUninit<S>; N]
Also add feature to test

d8718183b2 Create lang item array and add map fn
This creates the language item for arrays, and adds the map fn which is like map in options or
iterators. It currently allocates an extra array, unfortunately.

Added fixme for transmuting

Fix typo

Add drop guard

a2cfc74c5f Simplify array::IntoIter
- Initialization can use `transmute_copy` to do the bitwise copy.
- `as_slice` can use `get_unchecked` and `MaybeUninit::slice_get_ref`,
  and `as_mut_slice` can do similar.
- `next` and `next_back` can use the corresponding `Range` methods.
- `Clone` doesn't need any unsafety, and we can dynamically update the
  new range to get partial drops if `T::clone` panics.
