<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts/ProfHeap: Only allocate the Censuses that we need
When not LDV profiling there is no reason to allocate 32 Censuses; one
will do. This is a very small memory footprint optimisation, but it
comes for free.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts/ProfHeap: Free old allocations when reinitialising Censuses
Previously when not LDV profiling we would repeatedly reinitialise
`censuses[0]` with `initEra`. This failed to free the `Arena` and
`HashTable` from the old census, resulting in a memory leak.
Fixes #18348.

* Mention missing flags that are not actually enabled by -Wall (docs/users_guide/using-warnings.rst)
* Additionally remove -Wmissing-monadfail-instances from the list of flags enabled by -Wcompat, as it is not the case since 8.8

d535ef006d85dbdb7cda2b09c5bc35cb80108909 allowed the use of up to 10
vanilla registers but didn't update LLVM backend to support them. This
patch fixes it.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Improve handling of data type return kinds
Following a long conversation with Richard, this patch tidies up the
handling of return kinds for data/newtype declarations (vanilla,
family, and instance).
I have substantially edited the Notes in TyCl, so they would
bear careful reading.
Fixes #18300, #18357
In GHC.Tc.Instance.Family.newFamInst we were checking some Lint-like
properties with ASSSERT. Instead Richard and I have added
a proper linter for axioms, and called it from lintGblEnv, which in
turn is called in tcRnModuleTcRnM
New tests (T18300, T18357) cause an ASSERT failure in HEAD.
