The type variables in the holes fit output from
`abstract_refinement_hole_fits` is quite sensitive to compiler
configuration. Specifically, a slight change in the inlining
behavior of `throw` changes type variable naming in `(>>=)` and a few
others.
Ideally we would make hole fits output more deterministic but in the
meantime we simply normalise this difference away as it not relevant
to the test's goal.

As noted in #25066, the exception backtrace proposal introduced a rather
subtle performance regression due to simplification producing Core which
the demand analyser concludes may diverge with a precise exception. The
nature of the problem is more completely described in the new Note
[Hiding precise exception signature in throw].
The (rather hacky) solution we use here hides the problematic
optimisation through judicious use of `noinline`. Ultimately however we
will want a more principled solution (e.g. #23847).
Fixes #255066

If we have a broken symlink in the repository, don't try to `need` the symlink
or the target of the symlink. Attempting to do so has `shake` attempt to read the
target to compute its hash, which fails because the target doesn't exist.

Cabal 3.14 introduced a broken symlink in its testsuite. Unfortunately,
this broke our source distribution as we use use `tar --dereference` to avoid
issues with symlink compatibility on windows, and `tar --dereference` chokes
when it encounters any broken symlinks.
We can't get rid of `--dereference` because symlinks are generally broken on
windows, so the only option is to exclude this file from source archives.

Towards the goal of making the AST independent of GHC, this commit
starts the task of replacing usages of `FastString` with `Text` in the
AST (Language.Haskell.* modules).
Even though we /do/ want to use FastStrings -- critically in Names or Ids
-- there is no particular reason for the FastStrings that occur in the
AST proper to be FastStrings. Primarily, ...
