Rather than a list of constructors and a `NewOrData` flag, we define `data DataDefnCons a = NewTypeCon a | DataTypeCons [a]`, which enforces a newtype to have exactly one constructor.
Closes #22070.
Bump haddock submodule.

Emit a __builtin_unreachable() call after a foreign call marked as
CmmNeverReturns. This is crucial to generate correctly typed code for
wasm; as for other archs, this is also beneficial for the C compiler
optimizations.

We now always merge .a archives when ar supports -L.
This change is necessary in order to bootstrap GHC using GHC 9.4
on Windows, as nested archives aren't supported.
Not doing so triggered bug #21990 when trying to use the Win32
package, with errors such as:
Not a x86_64 PE+ file.
Unknown COFF 4 type in getHeaderInfo.
ld.lld: error: undefined symbol: Win32zm2zi12zi0zi0_SystemziWin32ziConsoleziCtrlHandler_withConsoleCtrlHandler1_info
We have to be careful about which ar is meant: in stage 0, the check
should be done on the system ar (system-ar in system.config).

Due to an oversight, the initial specification and implementation of
-Woperator-whitespace focused on varsym exclusively and completely
ignored consym.
This meant that expressions such as "x+ y" would produce a warning,
while "x:+ y" would not.
The specification was corrected in ghc-proposals pull request #404,
and this patch updates the implementation accordingly.
Regression test included.
