Basically, I think the information from the address sanitizer wiki (and the
other linked pages) should be integrated into the GCC manual, rather than the
manual referring to the wiki, such that the manual is self-contained.

The google code wiki only refers to LLVM, and it's not clear to the reader (to
me at least) if it is still being maintained (given that "Google Code will be
turning read-only") and to what extent it applies to GCC.

Moreover, the undefined behavior sanitizer runtime options (UBSAN_OPTIONS, as
described here
<https://www.chromium.org/developers/testing/undefinedbehaviorsanitizer>)
aren't documented at all in the manual.
