Try to reduce individual subtarget features in the "target-features" attribute. This attempts a textual removal of the fields in the string, not a semantic removal. Typically there's a lot of redundant feature spam in the feature list implied by the target-cpu (which I really wish clang would stop emitting). If we could parse these out, we could easily drop the fields without testing anything.
