This patch adds:
- the --optimistic-linking flag which binds unknown symbols in the
runtime linker to 0xDEADBEEF instead of exiting with failure
- The test T25240 which tests these flags using dead code in the FFI system.
- closes #25240
This patch is part of the upstreaming haskell.nix patches project.

This commit fixes an oversight of hadrian wrapper generation logic:
when doing cross compilation, `wrapper` is called on executable names
with cross prefix, therefore we must use `isSuffixOf` when matching to
take the cross prefix into account. Also add missing cross prefix to
ghci wrapper content and fix hsc2hs wrapper logic.

unsafeCoerce# doesn't exist at runtime so we should treat it like a Cast
for the purpose of mkTick.
This means if we have `{-# SCC foo #-} (unsafeCoerce# trivial_expr))` we
now push the scope part of the cost centre up to `trivial_expr` at which
point we can discard it completely if the expression is trivial enough.
This fixes #25212.

In 'DocStructureItem' we want to make sure the 'Avails' are sorted, for
interface file determinism. This commit introduces 'DetOrdAvails', a
newtype that should only be constructed by sorting Avails with
'sortAvails' unless the avails are known to be deterministically
ordered. This newtype is used by 'DocStructureItem' where 'Avails' was
previously used to ensure the list of avails is deterministically sorted
by construction.
Note: Even though we order the constructors and avails in the interface
file, the order of constructors in the haddock output is still
determined from the order of declaration in the source. This was also
true before, when the list of constructors in the interface file <docs>
section was non-deterministic. Some haddock tests such as
"ConstructorArgs" observe this (check the order of constructors in
out/ConstructorArgs.html vs src/ConstructorArgs.hs vs its interface file)
The updated tests are caused by haddock corners where the order in the
source is not preserved (and was non-deterministic before this PR):
* Module header in the latex backend
* Re-export of pattern synonyms associated to a datatype (#25342)
Fixes #25304
