Since we're going to approach integer overflow mitigation a type at a time, we need to enable all of the associated sanitizers, and then opt into types one at a time. Rename the existing "signed wrap" sanitizer to just the entire topic area: "integer wrap". Enable the implicit integer truncation sanitizers, with required callbacks and tests. Notably, this requires features (currently) only available in Clang, so we can depend on the cc-option tests to determine availability instead of doing version tests.

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.
