Ensure that trusted PTR_TO_BTF_ID accesses perform PROBE_MEM handling in raw_tp program. Without the previous fix, this selftest crashes the kernel due to a NULL-pointer dereference. Also ensure that dead code elimination does not kick in for checks on the pointer.

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.
