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.

RISCV64: Enable MulMayOflo_full test

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.

The test is failing for WASM32 and marked as fragile to not forget to
investigate this (#25249).
