No need for CURSES_INCLUDE_DIRS
This is a leftover from ef63ff27251a20ff11e58c9303677fa31e609a88

Replace Opt_SccProfilingOn flag with sccProfilingEnabled helper function
SCC profiling was enabled in a convoluted way: if WayProf was enabled,
Opt_SccProfilingOn general flag was set (in
`GHC.Driver.Ways.wayGeneralFlags`), and then this flag was queried in
various places.
There is no need to go via general flags, so this patch defines a
`sccProfilingEnabled :: DynFlags -> Bool` helper function that just
checks whether WayProf is enabled.

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.

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 flags that are not enabled by -Wall (#18372)
* 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

LLVM: support R9 and R10 registers
d535ef006d85dbdb7cda2b09c5bc35cb80108909 allowed the use of up to 10
vanilla registers but didn't update LLVM backend to support them. This
patch fixes it.
