<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">`genericIntMul2Op`: Call `genericWordMul2Op` directly
This unblocks a refactor, and removes partiality. It might be a PowerPC
regression but that should be fixable.

`genericIntMul2Op`, this is now an easy refactor.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">add -flink-rts flag to link the rts when linking a shared or static library #18072
By default we don't link the RTS when linking shared libraries because in the
most usual mode a shared library is an intermediary product, for example a
Haskell library, that will be linked into some executable in the end. So we
wish to defer the RTS flavour to link to the final link.
However sometimes the final product is the shared library, for example when
writing a plugin for some other system, so we do wish the shared library to
link the RTS.
For consistency we also make -staticlib honor this flag and its inversion.
-staticlib currently implies -flink-shared.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Give Uniq[D]FM a phantom type for its key.
This fixes #17667 and should help to avoid such issues going forward.
The changes are mostly mechanical in nature. With two notable
exceptions.
* The register allocator.
The register allocator references registers by distinct uniques.
However they come from the types of VirtualReg, Reg or Unique in
various places. As a result we sometimes cast the key type of the
map and use functions which operate on the now typed map but take
a raw Unique as actual key. The logic itself has not changed it
just becomes obvious where we do so now.
* <Type>Env Modules.
As an example a ClassEnv is currently queried using the types `Class`,
`Name`, and `TyCon`. This is safe since for a distinct class value all
these expressions give the same unique.
getUnique cls
getUnique (classTyCon cls)
getUnique (className cls)
getUnique (tcName $ classTyCon cls)
This is for the most part contained within the modules defining the
interface. However it requires us to play dirty when we are given a
`Name` to lookup in a `UniqFM Class a` map. But again the logic did
not change and it's for the most part hidden behind the Env Module.
Some of these cases could be avoided by refactoring but this is left
for future work.
We also bump the haddock submodule as it uses UniqFM.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">BigNum: rename BigNat types
Before this patch BigNat names were confusing because we had:
* GHC.Num.BigNat.BigNat: unlifted type used everywhere else
* GHC.Num.BigNat.BigNatW: lifted type only used to share static constants
* GHC.Natural.BigNat: lifted type only used for backward compatibility
After this patch we have:
* GHC.Num.BigNat.BigNat#: unlifted type
* GHC.Num.BigNat.BigNat: lifted type (reexported from GHC.Natural)
Thanks to @RyanGlScott for spotting this.
