 * Long integer shift.  This is different from the generic 32/64-bit
 * binary operations because vAA/vBB are 64-bit but vCC (the shift
 * distance) is 32-bit.  Also, Dalvik requires us to mask off the low
 * 6 bits of the shift distance.  x86 shifts automatically mask off
 * the low 5 bits of %cl, so have to handle the 64 > shiftcount > 31
 * case specially.
