If we go by this route, all the microarchitecture stuff will work only with Julia v1.4+, as this requires libllvm v8+. Not too bad since the alternative would be to have some code in Base to do the same, but that would require Julia v1.6 or more.

I don't want a hard failure if we can't determine the microarchitecture from the given set of features, but it's better to issue a warning just in case we're we're getting strange results. Also, this function would need to be used only when we're asking the set of features for an architecture we know we support (currently only x86_64), as done below in extended_platform_key_abi

Alternative to #6. This one is based on libLLVM and doesn't require extra packages
