In future version of clang, unsupported optimization flags are going to trigger a warning. They used to be silently ignored or triggering an error.

In Firefox build, we are unconditionally adding "-freorder-blocks" to the FLAGS showing a lot of warnings during build time:
clang: warning: optimization flag '-freorder-blocks' is not supported
