GHC.Tc.Solver had reached 4,000 lines -- although quite a lot of them
are comments.
This MR
* Adds the new module GHC.Tc.Solver.Default, which has all the
complex, but well modularised, defaulting code
* Moves a bit of code from GHC.Tc.Solver into the existing
GHC.Tc.Solver.Solve. Notably solveWanteds and simplifyWantedsTcM,
which are called from GHC.Tc.Solver.Default
It's a pure refactor. No code changes.

fixes #25266.

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.
