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/ghc!4853), this sets the
language for all the test files to `Haskell2010`. This should insolate
this test suite against changes to the default.

Make haddock more robust to changes to the `Language` data type

With the introduction of GHC2021, the `Languages` data type in GHC will
grow. In preparation of that (and to avoid changing haddock with each
new language), this change makes the code handle extensions to that data
type gracefully.

Backport "Plugin Haddock" to GHC-9.0 branch

alexbiehl-gc authored 4 years ago and Alex Biehl committed 4 years ago

I found that when running as a plugin the lookupName function (which
runs in Ghc monad) does not work correctly from the
typeCheckResultAction hook.

Instead, we abstracted the monad used when creating interfaces, so
that access to GHC session specific parts is explicit and so that the
TcM can provide their (correct) implementation of lookupName.

Backward compat: Add support for labeled module references

Support a markdown-style way of annotating module references. For instance

-- | [label]("Module.Name#anchor")

will create a link that points to the same place as the module
reference "Module.Name#anchor" but the text displayed on the link will
be "label".

Previously we were ignoring multiplicity and displayed
a %1 -> b as a -> b.
