WUCONCAT

Purpose: Concatenate slices of src1 and src2

DSZ8 → result[15:0] = src2[7:0],src1[7:0]
DSZ16 → result[31:0] = src2[15:0],src1[15:0]
DSZ32 → result[63:0] = src2[31:0],src1[31:0]

Example:

rbx = wuconcat.dsz16 (rax /*0xE5F555AAA5B5C5D5*/ , rcx /*0xE6F655AAA6B6C6D6*/)

result is rbx=00000000C6D6C5D5

Flags: 0

DSZ Modifier

DSZ8,DSZ16,DSZ32, DSZ64

Core2 issue

Core2 has sometimes DSZ modifier with value 180 (e.g. ADD.180, which seems to be similar to DSZ32)
