// MULSS - Multiply Scalar Single Precision Floating-Point Values
// MULSD - Multiply Scalar Double Precision Floating-Point Values
//
// MULSS multiplies the low single-precision (32-bit) floating-point value
// MULSD multiplies the low double-precision (64-bit) floating-point value
// Upper bits are preserved from the first source operand
//
// Opcodes:
// F3 0F 59 /r             MULSS xmm1, xmm2/m32     - Multiply scalar single from xmm2/m32 with xmm1
// F2 0F 59 /r             MULSD xmm1, xmm2/m64     - Multiply scalar double from xmm2/m64 with xmm1
