Also swap Trustworthy for Safe to placate -Wtrustworthy-safe
in ghc tests.

* Use unsafeNewArray_ instead of newAray_. We know we will fill the
  array, and newArray_ wastefully initializes it beforehand.
* Avoid safeIndexing the range when writing the elements. range
  generates the elements in the required order, so we can simply use an
  Int counter.

GHCJS uses the same representation for Addr# and StablePtr#, but not for
Int#.

In old GHC:

    I8# :: Int# -> Int8
    indexInt8OffAddr# :: Addr# -> Int# -> Int#
    ...

In upcoming GHC 9.2:

    I8# :: Int8# -> Int8
    indexInt8OffAddr# :: Addr# -> Int# -> Int8#
    ...

Both of those work with the last array release, where the only
requirement is merely that the constructor and primops agree, i.e.:

    exists alpha.
    I8# :: alpha -> Int8
    indexInt8OffAddr# :: Addr# -> Int# -> alpha

In current GHC HEAD, we had

    I8# :: Int8# -> Int8
    indexInt8OffAddr# :: Addr# -> Int# -> Int#

and it was only because `Int8# /= Int#` that we needed the commit being
reverted. we are about to fix the primops to match the constructors in
accordance with the final 9.2 design, and so we don't need that commit
anymore.

This reverts commit c7a696e3.

Release v0.5.4.0

Better late than never. Fixes #3.

As noted in #3, these were apparently released without ever making it
into a commit. Thankfully changes are pretty harmless.

Summary:
This matches exactly the 'Read (Array i e)' instance defined in base.
Note that the same thing is being done for 'Show (UArray i e)'.

Summary:
The old Travis script still had targets to test against GHC < 8.0,
and wasn't using Cabal `new-build` among other things.
