-fsanitize=[kernel-]address-sanitizer allows compile-time instrumentation of memory accesses to detect some classes of runtime undefined behavior. In preparation for allowing arches to provide infrastructure in support of this feature, add the generic KASAN options. These are only shown in the debug menu when the arch selects the appropriate symbol. The option is named equally to their Linux counterparts.
