Use new primops names for converting numbers to and from the native size

This is a companion to https://gitlab.haskell.org/ghc/ghc/-/merge_requests/4492.

I'm not sure why the second-to-top commit isn't already merged, as ghc HEAD relies on it.

The [CmmSized] adjust? I don't remember seeing PR for that. Ping @angerman?

@bgamari took over and said he'd do the submodule bumps, as I was unsure what exactly needed doing.

Sigh, indeed, mea culpa. It looks like the linter failed to catch this as the sized commit was reachable via a "permanent" ref on gitlab.haskell.org. @phadej, I'm afraid that either we will need to accept a merge commit here or push a tag to ensure that the existing commit remains reachable to ensure that GHC's history doesn't break.

Submodules are just awful.

Yeah I think if we just dispense with any hope of linear history and try to reconcile ghc-head branches with upstream master on an asynchronous basis, it will be the least bad.

The existing commit can be tagged with oops-keep-me.

I converted this to draft. Please mark is as ready when it really is.

(Side comment, the history looks awful, please cleanup it before marking as ready fore review).

In https://mail.haskell.org/pipermail/libraries/2021-February/031186.html I begin discussing this PR on the libraries list.

[phadej]

Fine. I'll merge this.
