A.5.300 SQRTSS: Scalar Single-Precision FP Square Root
SQRTSS xmm1,xmm2/m128 ; F3 0F 51 /r [KATMAI,SSE]
SQRTSS calculates the square root of the low-order single-precision FP
value from the source operand, and stores the single-precision result in
the destination register. The three high doublewords remain unchanged.
