qemu: add x86 cpu

This patch adds a qemu x86 cpu chip.  It has no initialization function
as this isn't needed on virtual hardware.  A virtual machine can have
pretty much any CPU: qemu emulates a wide range of x86 CPUs (try 'qemu
-cpu ? for a list), also with 'qemu -cpu host' the guest will see a cpu
which is (almost) identical to the one on the host machine.  So I've
added X86_VENDOR_ANY as wildcard match for the cpu_table.
