The first change makes the array ones use the proper fixed-size types,
which also means that just like before, they can be used without
explicit conversions with the boxed sized types. (Before, it was Int# /
Word# on both sides, now it is fixed sized on both sides).
For the second change, don't use "extend" or "narrow" in some of the
user-facing primops names for conversions.
- Names like `narrowInt32#` are misleading when `Int` is 32-bits.
- Names like `extendInt64#` are flat-out wrong when `Int is
32-bits.
- `narrow{Int,Word}<N>#` however map a type to itself, and so don't
suffer from this problem. They are left as-is.
These changes are batched together because Alex happend to use the array
ops. We can only use released versions of Alex at this time, sadly, and
I don't want to have to have a release thatwon't work for the final GHC
9.2. So by combining these we get all the changes for Alex done at once.
Bump hackage state in a few places, and also make that workflow slightly
easier for the future.
Bump minimum Alex version
Bump Cabal, array, bytestring, containers, text, and binary submodules

This replaces all Word<N> = W<N># Word# and Int<N> = I<N># Int# with
Word<N> = W<N># Word<N># and Int<N> = I<N># Int<N>#, thus providing us
with properly sized primitives in the codegenerator instead of pretending
they are all full machine words.
This came up when implementing darwinpcs for arm64. The darwinpcs reqires
us to pack function argugments in excess of registers on the stack. While
most procedure call standards (pcs) assume arguments are just passed in
8 byte slots; and thus the caller does not know the exact signature to make
the call, darwinpcs requires us to adhere to the prototype, and thus have
the correct sizes. If we specify CInt in the FFI call, it should correspond
to the C int, and not just be Word sized, when it's only half the size.
This does change the expected output of T16402 but the new result is no
less correct as it eliminates the narrowing (instead of the `and` as was
previously done).
Bumps the array, bytestring, text, and binary submodules.
