KVM: x86 emulator: Add DstAcc operand type

Add DstAcc operand type. That means that there are 4 bits now for
DstMask.

"In the good old days cpus would have only one register that was able to
 fully participate in arithmetic operations, typically called A for
 Accumulator.  The x86 retains this tradition by having special, shorter
 encodings for the A register (like the cmp opcode), and even some
 instructions that only operate on A (like mul).

 SrcAcc and DstAcc would accommodate these instructions by decoding A
 into the corresponding 'struct operand'."
