This reverts commit 4512ad2d6a8e65ea43c86c816411cb13b822f674.
This was never applied to master/9.6 originally.

* Introduce refactorDupsOn f = refactorDups (comparing f)
* Make mkBigTupleCase and coreCaseTuple monadic.
Every call to those functions was preceded by calling newUniqueSupply.
* Use mkUserLocalOrCoVar, which is equivalent to combining
mkLocalIdOrCoVar with mkInternalName.

Despite Cabal supporting any architecture name, `cabal --check` only
supports a few built-in ones. Sadly `cabal --check` is used by Hackage
hence using any non built-in name in a package (e.g. `arch(js)`) is
rejected and the package is prevented from being uploaded on Hackage.
Luckily built-in support for the `javascript` architecture was added for
GHCJS a while ago. In order to allow newer `base` to be uploaded on
Hackage we make the switch from `js` to `javascript` architecture.
Fixes #22740.

Reference ticket #21766
This commit restructures IPE buffer list entries to not contain
references to their corresponding info tables. IPE buffer list nodes now
point to two lists of equal length, one holding the list of info table
pointers and one holding the corresponding entries for each info table.
This will allow the entry data to be compressed without losing the
references to the info tables.

Capacity of buffers allocated for decompressed IPE data was

the size of the compressed data.
