The vneg instruction should also be supported by the disassembler (see
Decoder::DecodeTypeVFP in disasm-arm.cc). Currently, the disassembler will only
print "unknown". 

Please also add a test in test-disasm-arm.cc.

Done.

   void vabs(const DwVfpRegister dst,
             const DwVfpRegister src,
             const Condition cond = al);
