Closes #17209. This implements GHC Proposal 541, allowing a WARNING
pragma to be annotated with a category like so:
{-# WARNING in "x-partial" head "This function is undefined on empty lists." #-}
The user can then enable, disable and set the severity of such warnings
using command-line flags `-Wx-partial`, `-Werror=x-partial` and so on. There
is a new warning group `-Wextended-warnings` containing all these warnings.
Warnings without a category are treated as if the category was `deprecations`,
and are (still) controlled by the flags `-Wdeprecations`
and `-Wwarnings-deprecations`.
Updates Haddock submodule.

Previously the predicate for determining whether a logical instruction
operand could be encoded as a bitmask immediate was far too
conservative. This meant that, e.g., pointer untagged required five
instructions whereas it should only require one.
Fixes #23030.

For a long time, `GHC.Conc.Sync` has said
```haskell
-- ToDo: data ThreadId = ThreadId (Weak ThreadId#)
-- But since ThreadId# is unlifted, the Weak type must use open
-- type variables.
```
We are now actually capable of using `Weak# ThreadId#`, but the
world has moved on. To support the `Show` and `Ord` instances, we'd
need to store the thread ID number in the `ThreadId`. And it seems
very difficult to continue to support `threadStatus` in that regime,
since it needs to be able to explain how threads died. In addition,
garbage collection of weak references can be quite expensive, and it
would be hard to evaluate the cost over he whole ecosystem. As discussed
in
[this CLC issue](https://github.com/haskell/core-libraries-committee/issues/125),
it doesn't seem very likely that we'll actually switch to weak
references here.

- Make hs_perform_gc call performBlockingMajorGC, which restores
previous behavior
- Use hs_perform_gc in ffi023
- Remove rts_clearMemory() call in ffi023, it now works again in some
