Unfortunately, the SQL spec is perfectly clear that you pad or strip
zero bits on the *right* of the bit string. We cannot change that.
It might have been better if we had defined int<->bit casts to treat
the first bit of the bit string as the LSB of the integer. But we
didn't, and it's probably too big a change to consider.
