Justin Bogner 92e82c5733 cmake: Only sanitize use-after-scope if the host compiler supports it
In r292256, we started adding -fsanitize-use-after-scope when using
the address sanitizer, but that flag wasn't always available. This
fixes the config to only add the flag if the host compiler supports
it.
