We just fixed an issue where changing the SVE VL while SME was active could result in us attempting to save the streaming mode SVE vectors without any backing storage. Add a test case which provokes that issue, ideally we should also verify that the contents of ZA are unaffected by any of what we did. Note that since we need to keep streaming mode enabled we can't use any syscalls to trigger the issue, we have to sit in a loop in usersapce and hope to be preempted. The chosen numbers trigger with defconfig on all the virtual platforms for me, this won't be 100% on all systems but avoid an overcomplicated test implementation.

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.
