Adds sanitizer support for the xlC compiler
- Option "--with-sanitizers" sets compiler flag "-qcheck=all"
- Alternatively "--enable-sanitizers" can be set to either "address" which
translates to "-qcheck=bounds:stackclobber:unset" or "undefined" which
sets the flags "-qcheck=nullptr:divzero".
The flags are explained here: https://www.ibm.com/support/knowledgecenter/SSGH2K_13.1.2/com.ibm.xlc131.aix.doc/compiler_ref/opt_check.html
Currently compiling with "--with-sanitizers" or
"--enable-sanitizers=undefined" will cause compilation to fail because of a
"possible division by 0" in `Botan::bigint_divop`. This seems to be a false
positive, before the division occurrs an Invalid_Argument exception will be
thrown.
