Use static calls to improve kvm_x86_ops performance. Introduce the definitions that will be used by a subsequent patch to actualize the savings. Add a new kvm-x86-ops.h header that can be used for the definition of static calls. This header is also intended to be used to simplify the defition of svm_kvm_ops and vmx_x86_ops. Note that all functions in kvm_x86_ops are covered here except for 'pmu_ops' and 'nested ops'. I think they can be covered by static calls in a simlilar manner, but were omitted from this series to reduce scope and because I don't think they have as large of a performance impact.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
