This patch adds the assembly/disassembly for the following instructions:

zipq1 : Interleave elements from low halves of each pair of quadword vector segments
zipq2 : Interleave elements from high halves of each pair of quadword vector segments
uzpq1 : Concatenate even elements within each pair of quadword vector segments
uzpq2 : Concatenate odd elements within each pair of quadword vector segments
tblq  : Programmable table lookup within each quadword vector segment (zeroing)
