cmd/intarnal/obj: add new assembly format for VANDV and VANDB on loong64

Browse source 
In order to make it easier to write in assembly and to be consistent
with the usage of general instructions, a new assembly format is
added for the instructions VANDV and VANDB.

It also works for instructions XVAND{V,B}, [X]V{OR,XOR,NOR,ANDN,ORN}V
and [X]V{OR,XOR,NOR}B.
