Reland Produce warning for performing pointer arithmetic on a null pointer.
Summary:
Test and produce warning for subtracting a pointer from null or subtracting
null from a pointer.
This reland adds the functionality that the warning is no longer reusing an
existing warning, it has different wording for C vs C++ to refect the fact
that nullptr-nullptr has defined behaviour in C++, it is suppressed
when the warning is triggered by a system header and adds
-Wnull-pointer-subtraction to allow the warning to be controlled. -Wextra
implies -Wnull-pointer-subtraction.
