    Dont use big/small-int primops on IL32P64 (i.e. Win/x86_64) for now
    
    This is due to `mpz_*()` functions having @long@ arguments which are
    32bit on IL32P64, whereas `Int#` and `Word#` are 64bit wide, causing all
    sorts of malfunction due to truncation.
    
    This affects mostly the new big/small-int primops introduced in the
    course of #8647, so when `SIZEOF_W != SIZEOF_LONG` we simply fall back
    to using the big/big-int primops. big/small primops implemented via the
    low-level `mpn_*()` GMP operations are not affected, as those use
    `mp_limb_t` arguments.
