  target-s390x: fix MOVE LONG instruction

The MOVE LONG instruction should pad the destination operand with the
byte from bit positions 32-39 of the source length (r2 + 1), not with
the same byte in the source address.

  target-s390x: fix CONVERT TO BINARY (CVD, CVDY)

current_number being shift left by more than 32 bits, we can't use a
simple int. Similarly use an int64_t type for the input binary value,
to not get the -2^31 case wrong. Finally don't initialize shift to 4,
it's already done in the for loop.
