Instruction
PSRAW xmm, xmm
Synopsis
 _mm_sra_epi16(__m128i a, __m128i count);
Description
Shift packed 16-bit integers in "a" right by "count" while shifting in sign bits, and store the results in "dst".
Operation
FOR j := 0 to 7
	i := j*16
	IF count[63:0] > 15
		dst[i+15:i] := (a[i+15] ? 0xFFFF : 0x0)
	ELSE
		dst[i+15:i] := SignExtend16(a[i+15:i] >> count[63:0])
	FI
