The function prototype kvm_skip_instr32() is used only by the hyp code, so
it makes more sense to live in the hyp specific header file adjust_pc.h.
Since __adjust_pc() has been moved to kvm_asm.h so it can be used by the
generic code, rename adjust_pc.h -> skip_instr.h to avoid confusion and to
better reflect the purpose of the remaining functions.
