Expand description

Shifts each element of left by a scalar amount. The shift amount is determined by the lowest 64 bits of right (which is a 128-bit vector).

For logic shifts, when right is larger than BITS - 1, zero is produced. For arithmetic right-shifts, when right is larger than BITS - 1, the sign bit is copied to all bits.
