testsuite: introduce 'static_stats' tests

They are a particular type of perf tests. This patch introduces a
'stats_files_dir' configuration field in the testsuite driver where all
haddock timing files (and possibly others in the future) are assumed to live.
We also change both the Make and Hadrian build systems to pass respectively
$(TOP)/testsuite/tests/perf/haddock/ and
<build root>/stage1/haddock-timing-files/ as the value of that new
configuration field, and to generate the timing files in those directories
in the first place while generating documentation with haddock.

This new test type can be seen as one dedicated to examining stats files that
are generated while building a GHC distribution. This also lets us get rid of
the 'extra_files' directives in the all.T entries for haddock.base,
haddock.Cabal and haddock.compiler.

Fix some warnings in users_guide (incl #16640)

- short underline
- :ghc-flag:, not :ghc-flags:
- :since: have to be separate
- newline before code block
- workaround anchor generation so

    - pragma:SPECIALISE
    - pragma:SPECIALIZE-INLINE
    - pragma:SPECIALIZE-inline

  are different anchors, not all the same `pragma:SPECIALIZE`

In hole fits, don't show VTA for inferred variables (#16456)

We fetch the ArgFlag for every argument by using splitForAllVarBndrs
instead of splitForAllTys in unwrapTypeVars.

Fix missing unboxed tuple RuntimeReps (#16565)

Unboxed tuples and sums take extra RuntimeRep arguments,
which must be manually passed in a few places.
This was not done in deSugar/Check.

This error was hidden because zipping functions in TyCoRep
ignored lists with mismatching length. This is now fixed;
the lengths are now checked by calling zipEqual.

As suggested in #16565, I moved checking for isTyVar and
isCoVar to zipTyEnv and zipCoEnv.

Allow using tagetContents for modules needing preprocessing

This allows GHC API clients, most notably tooling such as
Haskell-IDE-Engine, to pass unsaved files to GHC more easily.

Currently when targetContents is used but the module requires preprocessing
'preprocessFile' simply throws an error because the pipeline does not
support passing a buffer.

This change extends `runPipeline` to allow passing the input buffer into
the pipeline. Before proceeding with the actual pipeline loop the input
buffer is immediately written out to a new tempfile.

I briefly considered refactoring the pipeline at large to pass around
in-memory buffers instead of files, but this seems needlessly complicated
since no pipeline stages other than Hsc could really support this at the
moment.

downsweep: Allow TargetFile not to exist when a buffer is given

Currently 'getRootSummary' will fail with an exception if a 'TargetFile' is
given but it does not exist even if an input buffer is passed along for
this target.

In this case it is not necessary for the file to exist since the buffer
will be used as input for the compilation pipeline instead of the file
anyways.
