is 1 bit and the Index field is the remaining 15 bits, with TI=0 meaning
GDT and TI=1 meaning LDT.

HVFX86EmulatorState carries it's own copy of x86 registers. It can be
dropped in favor of regs in generic CPUX86State.

The field is used to print address of instructions that have no parser
in decode_invalid(). RIP from VMCS is saved into fetch_rip before
decoding starts but it's also saved into env->eip in load_regs().
Therefore env->eip can be used instead of fetch_rip.
While at it, correct address printed in decode_invalid(). It prints an
address before the unknown instruction.
