Matthew Auld bf74a18ca8 drm/i915/gem: Introduce a selftest for the gem object migrate functionality
A selftest for the gem object migrate functionality. Slightly adapted
from the original by Matthew to the new interface and new fill blit
code.

v4:
- Initialize buffers and check contents after migration
  (Suggested by Matthew Auld)
- Perform async migration (if implemented) in the igt_lmem_pages_migrate
  test
- Test also migration to the current region.

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.
