Since 54250f2d8de910b094070c1b48f086030df634b1 we expected T4267 to
fail, but it passes on CI.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Require GHC 8.8 as the minimum compiler for bootstrapping
This allows us to remove several bits of CPP that are either always
true or no longer reachable. As an added bonus, we no longer need to
worry about importing `Control.Monad.Fail.fail` qualified to avoid
clashing with `Control.Monad.fail`, since the latter is now the same
as the former.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Add regression test for #17963
The panic in #17963 happened to be fixed by commit
e3c374cc5bd7eb49649b9f507f9f7740697e3f70. This patch adds a
regression test to ensure that it remains fixed.
Fixes #17963.

The combinator andM is used only once, and the code is shorter and

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">base: Ensure that encoding global variables aren't inlined
As noted in #17970, these (e.g. `getFileSystemEncoding` and
`setFileSystemEncoding`) previously had unfoldings, which would
break their global-ness.
While not strictly necessary, I also add a NOINLINE on
`initLocaleEncoding` since it is used in `System.IO`, ensuring that we
only system's query the locale encoding once.
Fixes #17970.

Before, there were two distinct Notes named
"Eta reduction for data families". This renames one of them to
"Implementing eta reduction for data families" to disambiguate the
two and fixes references in other parts of the codebase to ensure
that they are pointing to the right place.
Fixes #17313.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Cross-module LambdaFormInfo passing
- Store LambdaFormInfos of exported Ids in interface files
- Use them in importing modules
This is for optimization purposes: if we know LambdaFormInfo of imported
Ids we can generate more efficient calling code, see `getCallMethod`.
Exporting (putting them in interface files or in ModDetails) and
importing (reading them from interface files) are both optional. We
don't assume known LambdaFormInfos anywhere and do not change how we
call Ids with unknown LambdaFormInfos.
