Performs an interleaved unpack of the high-order single-precision floating-point values from the source operand (second operand) and the destination operand (first operand).

The source operand can be an XMM register or a 128-bit memory location; the destination operand is an XMM register.

When unpacking from a memory operand, an implementation may fetch only the appropriate 64 bits; however, alignment to 16-byte boundary and normal segment checking will still be enforced.

Destination[0..31] = Destination[64..95];
Destination[32..63] = Source[64..95];
Destination[64..95] = Destination[96..127];
Destination[96..127] = Source[96..127];
