Now that KVM selftests enable all supported XCR0 features by default, add a testcase to the XCR0 vs. CPUID test to verify that the guest can disable everything except the legacy FPU in XCR0, and then re-enable the full feature set, which is kinda sorta what the test did before XCR0 was setup by default.

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 reStructuredText 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.
