Allow unsaturated runRW# applications

Previously we had a very aggressive Core Lint check which caught
unsaturated applications of runRW#. However, there is nothing
wrong with such applications and they may naturally arise in desugared
Core. For instance, the desugared Core of Data.Primitive.Array.runArray#
from the `primitive` package contains:

    case ($) (runRW# @_ @_) (\s -> ...) of ...

In this case it's almost certain that ($) will be inlined, turning the
application into a saturated application. However, even if this weren't
the case there isn't a problem: CorePrep (after deleting an unnecessary
case) can simply generate code in its usual way, resulting in a call to
the Haskell definition of runRW#.

Fixes #18291.

install: do not install sphinx doctrees

These files are 100% not needed at install time, and they contain
unreproducible info. See https://reproducible-builds.org/ for why this
matters.

testsuite: Only run llvm ways if llc is available

As noted in #18560, we previously would always run the LLVM ways since
`configure` would set `SettingsLlcCommand` to something non-null when
it otherwise couldn't find the `llc` executable. Now we rather probe for
the existence of the `llc` executable in the testsuite driver.

Fixes #18560.

DynFlags: refactor GHC.CmmToAsm (#17957, #10143)

This patch removes the use of `sdocWithDynFlags` from GHC.CmmToAsm.*.Ppr

To do that I've had to make some refactoring:

* X86' and PPC's `Instr` are no longer `Outputable` as they require a
  `Platform` argument

* `Instruction` class now exposes `pprInstr :: Platform -> instr -> SDoc`

* as a consequence, I've refactored some modules to avoid .hs-boot files

* added (derived) functor instances for some datatypes parametric in the
  instruction type. It's useful for pretty-printing as we just have to
  map `pprInstr` before pretty-printing the container datatype.
