[Eric Auger]

Add the basic infrastructure needed to test AMD nested SVM.
Also add a first basic vmcall test.

Best regards

Eric

History:
v3 -> v4:
- gpr64_regs struct just contains 64b mode GPRs ordered
  as in x86_register
- cleanup in run_guest (vm* instructions) and reduce
  clubber list.
- add some comments

v2 -> v3:
- Took into account Vitaly's comment:
  - added "selftests: KVM: Replace get_gdt/idt_base() by
    get_gdt/idt()"
  - svm.h now is a copy of arch/x86/include/asm/svm.h
  - avoid duplicates

v1 -> v2:
- split into 2 patches
- remove the infrastructure to run low-level sub-tests and only
  keep vmmcall's one.
- move struct regs into processor.h
- force vmcb_gpa into rax in run_guest()
