(cherry picked from commit cafb4811)

It is not clear to me whether the original was printing
incorrectly (since we did not have the TopLevel flag before now), or
if this behaviour is expected.

For the time being I am assuming the former.

As landed via ghc/ghc!2418

This catches up to GHC using the new extractTHDocs function, which
returns documentation added via the putDoc function (provided it was
compiled with Opt_Haddock). Since it's already a map from names -> docs,
there's no need to do traversal etc.
It also matches the change from the argument map being made an IntMap
rather than a Map Int

Fix haddockHypsrcTest output in ghc-head

Fix the call-site of guessTarget in Interface.hs

Explicit the imports from GHC.HsToCore.Docs

This prevents noLoc's appearing in the ParsedSource.

Match the change in GHC.

Explicit imports for Haddock.Interface and Haddock.Interface.Create

[ghc-head] Clean-up of Interface and Interface.Create's imports and pragmata 

html-test: Always set language

from ghc-9.2 on, the “default” langauge of GHC is expected to change
more wildly. To prepare for that (and unblock
ghc!4853), this sets the
language for all the test files to `Haskell2010`. This should insolate
this test suite against changes to the default.
