Silence x-partial in Haddock.Backends.Xhtml

This is an unfortunate consequence of two mechanisms:
  * GHC provides (possibly-empty) lists of names
  * The functions that retrieve those names are not equipped to do error
    reporting, and thus accept these lists at face value. They will have
    to be attached an effect for error reporting in a later refactoring

hadrian: Support loading haddock in ghci

There is one tricky aspect with wired-in packages where the boot package
is built with `-this-unit-id ghc` but the dependency is reported as
`-package-id ghc-9.6...`. This has never been fixed in GHC as the
situation of loading wired-in packages into the multi-repl seems like
quite a niche feature that is always just easier to workaround.

hadrian/multi: Load all targets when ./hadrian/ghci-multi is called

This seems to make a bit more sense than just loading `ghc` component
(and dependencies).

ci: Beef up determinism interface test

There have recently been some determinism issues with the simplifier and
documentation. We enable more things to test in the ABI test to check
that we produce interface files deterministically.

Adjust test timings for slower computers

Increase the delays a bit to be able to run these tests on slower
computers.

The reference was a Lichee Pi 4a RISCV64 machine.

RISCV64: Ignore divbyzero test

The architecture's behaviour differs from the test's expectations. See
comment in code why this is okay.

It works and thus can be tested.

RISCV64: LibffiAdjustor: Ensure code caches are flushed

RISCV64 needs a specific code flushing sequence (involving fence.i) when
new code is created/loaded.

RISCV64: Add additional linker symbols for builtins

We're relying on some GCC/Clang builtins. These need to be visible to
the linker (and not be stripped away.)

RISCV64: Add GHCi support

As we got a RTS linker for this architecture now, we can enable GHCi for
it.

Add test for C calling convention

Ensure that parameters and return values are correctly processed. A
dedicated test (like this) helps to get the subtleties of calling
conventions easily right.
