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

faddqv   : Floating-point add recursive reduction of quadword vector segments
fmaxqv   : Floating-point maximum reduction of quadword vector segments
fmaxnmqv : Floating-point maximum number recursive reduction of quadword vector segments
fminqv   : Floating-point minimum recursive reduction of quadword vector segments
fminnmqv : Floating-point minimum number recursive reduction of quadword vector segments
