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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@292423 91177308-0d34-0410-b5e6-96231b3b80d8 Justin Bogner 3 years ago
