[Clang] Adjust pointer-overflow sanitizer for N3322 (#120719)
N3322 makes NULL + 0 well-defined in C, matching the C++ semantics.
Adjust the pointer-overflow sanitizer to no longer report NULL + 0 as a
pointer overflow in any language mode. NULL + nonzero will of course
continue to be reported.
As N3322 is part of
https://www.open-std.org/jtc1/sc22/wg14/www/previous.html, and we never
performed any optimizations based on NULL + 0 being undefined in the
first place, I'm applying this change to all C versions.
