This is complementary to the "STATIC_ANALYSIS" macro defined in "internal.h", but not as straight-forward to detect: clang defines "__has_feature(address_sanitizer)" if the address sanitizer is enabled. "__has_feature" is clang specific and does not exist in gcc (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60512) gcc, depending on the version, defines "__SANITIZE_ADDRESS__ 1" if compiled with the address sanitizer enabled. No similar macro is defined for the undefined behavior sanitizer. Instead, let meson set this symbol.
