Fix ghc-bignum exceptions
We must ensure that exceptions are not simplified. Previously we used:
case raiseDivZero of
_ -> 0## -- dummyValue
But it was wrong because the evaluation of `raiseDivZero` was removed and
the dummy value was directly returned. See new Note [ghc-bignum exceptions].
I've also removed the exception triggering primops which were fragile.
We don't need them to be primops, we can have them exported by ghc-prim.
I've also added a test for #18359 which triggered this patch.
