Add macro definition functions DEF_SIGHANDLER_FUNC() and DEF_INST_RAISE_SIG() helpers. Furthermore, there is no need to modify the default SIGILL handling function throughout the entire testing lifecycle in the main() function. It is reasonable to narrow the scope to the context of the sig_fn function only. This is a pre-patch for the subsequent SIGBUS handler patch.

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.
