<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #16282.
Previously, -W(all-)missed-specs was created with 'NoReason',
so no information about the flag was printed along with the warning.
Now, -Wall-missed-specs is listed as the Reason if it was set,
otherwise -Wmissed-specs is listed as the reason.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Generate straightline code for inline array allocation
GHC has an optimization for allocating arrays when the size is
statically known -- it'll generate the code allocating and initializing
the array inline (instead of a call to a procedure from
`rts/PrimOps.cmm`).
However, the generated code uses a loop to do the initialization. Since
we already check that the requested size is small (we check against
`maxInlineAllocSize`), we can generate faster straightline code instead.
This brings about 15% improvement for `newSmallArray#` in my testing and
slightly simplifies the code in GHC.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix #16500: look for interface files in -hidir flag in OneShot mode
We are currently ignoring options set in the hiDir field of hsc_dflags
when looking for interface files while compiling in OneShot mode. This
is inconsistent with the behaviour of other directory redirecting fields
(such as objectDir or hieDir). It is also inconsistent with the
behaviour of compilation in CompManager mode (a.k.a `ghc --make`) which
looks for interface files in the directory set in hidir flag. This
changes Finder.hs so that we use the value of hiDir while looking for
interface in OneShot mode.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Make `singleConstructor` cope with pattern synonyms
Previously, `singleConstructor` didn't handle singleton `COMPLETE` sets
of a single pattern synonym, resulting in incomplete pattern warnings
in #15753.
This is fixed by making `singleConstructor` (now named
`singleMatchConstructor`) query `allCompleteMatches`, necessarily making
it effectful. As a result, most of this patch is concerned with
threading the side-effect through to `singleMatchConstructor`.
Unfortunately, this is not enough to completely fix the original
reproduction from #15753 and #15884, which are related to function
applications in pattern guards being translated too conservatively.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">settings.in: Reformat
We're might be about to switch to generating it in Hadrian/Make. This
reformat makes it easier to programmingmatically generate and end up
with the exact same thing, which is good for diffing to ensure no
regressions.
I had this as part of !712, but given the difficulty of satisfying CI, I
figured I should break things up even further.
