<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.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Simplify `PrimopCmmEmit`
Follow @simonpj's suggestion of pushing the "into regs" logic into
`emitPrimOp`. With the previous commit getting rid of the recursion in
`genericIntMul2Op`, this is now an easy refactor.

We shouldn't directly call 'genericWordMul2Op' in genericIntMul2Op

better use it!

<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;">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.
