<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.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Use ADTs for parser errors/warnings
Haskell and Cmm parsers/lexers now report errors and warnings using ADTs
defined in GHC.Parser.Errors. They can be printed using functions in
GHC.Parser.Errors.Ppr.
Some of the errors provide hints with a separate ADT (e.g. to suggest to
turn on some extension). For now, however, hints are not consistent
across all messages. For example some errors contain the hints in the
main message. I didn't want to change any message with this patch. I
expect these changes to be discussed and implemented later.
Surprisingly, this patch enhances performance. On CI
(x86_64/deb9/hadrian, ghc/alloc):

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Don't attach CPR signatures to NOINLINE data structures (#18154)
Because the generated `KindRep`s don't have an unfolding, !3230 did not
actually stop to compute, attach and serialise unnecessary CPR
signatures for them. As already said in
`Note [CPR for data structures]`, that leads to bloated interface
files which is ultimately quadratic for Nested CPR.
So we don't attach any CPR signature to bindings that
* Are not thunks (because thunks are not in WHNF)
* Have arity 0 (which means the top-level constructor is not a lambda)
If the data structure has an unfolding, we continue to look through it.
If not (as is the case for `KindRep`s), we look at the unchanged CPR
signature and see `topCprType`, as expected.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Inline `decodeDoubleInteger` and constant-fold `decodeDouble_Int64#` instead
Currently, `decodeDoubleInteger` is known-key so that it can be
recognised in constant folding. But that is very brittle and doesn't
survive worker/wrapper, which we even do for
`NOINLINE`/`CONSTANT_FOLDED` things since #13143.
Also it is a trade-off: The implementation of `decodeDoubleInteger`
allocates an `Integer` box that never cancels aways if we don't inline
it.
Hence we recognise the `decodeDouble_Int64#` primop instead in constant
folding, so that we can inline `decodeDoubleInteger`.
You may wonder how this affects performance of code using
`integer-simple`; Apparently, according to @hsyl20 this is not a concern
since we will hopefully land !2231 soon.
Fixes #18092.
