For svmul, if one of the operands is a constant vector with a uniform
power of 2, this patch folds the multiplication to a left-shift by
immediate (svlsl).
Because the shift amount in svlsl is the second

For svmul, if one of the operands is a constant vector with a uniform
power of 2, this patch folds the multiplication to a left-shift by
immediate (svlsl).
Because the shift amount in svlsl is the second operand, the order of the
operands is switched, if the first operand contained the powers of 2.
