<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">PmCheck: Long-distance information for LocalBinds (#18626)
Now `desugarLocalBind` (formerly `desugarLet`) reasons about
* `FunBind`s that
* Have no pattern matches (so which aren't functions)
* Have a singleton match group with a single GRHS
* (which may have guards)
* and looks through trivial post-typechecking `AbsBinds` in doing so
to pick up the introduced renamings.
And desugars to `PmLet` LYG-style guards. Since GRHSs are no longer
denoted simply by `NonEmpty PmGRHS`, but also need to carry a `[PmGrd]`
for the `PmLet`s from `LocalBind`s, I added `PmGRHSs` to capture that.
Since we call out to the desugarer more often, I found that there were
superfluous warnings emitted when desugaring e.g. case expressions.
Thus, I made sure that we deactivate any warnings in the LYG desugaring
steps by the new wrapper function `noCheckDs`.
There's a regression test in `T18626`. Fixes #18626.
