This is a bit of a shot in the dark to fix #24033, which appears to be
another instance of #21712. For some reason the ld-override logic
*still* appears to be active on Darwin targets (or at least one).
Consequently, on misconfigured systems we may choose a non-`ld64`
linker.
It's a bit unclear exactly what happened in #24033 but ultimately the
check added for #21712 was not quite right, checking for the
`ghc_host_os` (the value of which depends upon the bootstrap compiler)
instead of the target platform. Fix this.
Fixes #24033.

This reverts commit 1c18d3b41f897f34a93669edaebe6069f319f9e2.
`-optP` should pass options to the preprocessor, that might be a very
different program to the C compiler, so passing the options to the C
compiler is likely to result in `-optP` being useless.

locations in their IPE info. Now they do.

The class is defined as
class HasAnnotation e where
noAnnSrcSpan :: SrcSpan -> e
This generalises noAnnSrcSpan, and allows
noLocA :: (HasAnnotation e) => a -> GenLocated e a
noLocA = L (noAnnSrcSpan noSrcSpan)

This commit introduces a language extension, `OrPatterns`, as described in proposal 0522.
It extends the syntax by the production
`pat -> (one of pat1, ..., patk)`.
The or-pattern `pat` succeeds iff one of the patterns `pat1`, ..., `patk` succeed, in this order.
Currently, or-patterns cannot bind variables. They are still of great use as they discourage the use of wildcard patterns in favour of writing out all "default" cases explicitly:
```
isIrrefutableHsPat pat = case pat of
...
(one of WildPat{}, VarPat{}, LazyPat{})
= True
(one of PArrPat{}, ConPatIn{}, LitPat{}, NPat{}, NPlusKPat{}, ListPat{})
= False
```
This makes code safer where data types are extended now and then - just like GHC's `Pat` in the example when adding the new `OrPat` constructor. This would be catched by `-fwarn-incomplete-patterns`, but not when a wildcard pattern was used.
- Update submodule haddock.
