c++: Ignore __sanitizer_ptr_{sub,cmp} builtin calls during constant expression evaluation [PR97145]
These two builtin calls are added already during parsing before pointer
subtractions or comparisons, normally they perform runtime verification
of whether the pointers point to the same object or different objects,
but during constant expressione valuation we don't really need those
builtins for anything.

* constexpr.c (cxx_eval_builtin_function_call): Return void_node for
calls to __sanitize_ptr_{sub,cmp} builtins.
* g++.dg/asan/pr97145.C: New test.
