Andrii Nakryiko 882e3d873c selftests/bpf: add iter test requiring range x range logic
Add a simple verifier test that requires deriving reg bounds for one
register from another register that's not a constant. This is
a realistic example of iterating elements of an array with fixed maximum
number of elements, but smaller actual number of elements.

This small example was an original motivation for doing this whole patch
set in the first place, yes.

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.
