Enable AddressSanitizer on arm-unknown-linux-gnueabihf and armv7-unknown-linux-gnueabihf

Add SanitizerSet::ADDRESS to the supported_sanitizers for the arm-unknown-linux-gnueabihf and armv7-unknown-linux-gnueabihf targets.

The AddressSanitizer is already enabled on the armv7-linux-androideabi platform, which shares the same ARM architecture. There is no reason these Linux GNU targets should not also support it, as the underlying LLVM support for ASan on 32-bit ARM is already in place.
