Is it a good idea to use 64-bit limbs and 64-bit alignment for the ia32 ABI? I mean, it is fine to use that _BitInt(N) for N 33..64 has size/alignment/passing of long long, but wonder if for N > 64 the ABI shouldn't use 32-bit limbs, 32-bit alignments and passing as struct containing the 32-bit limbs.
