[PATCH] D104107: [NFCI][X86] Drop "atom"/"slm" target tuning "features", derive them from CPU string

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I've no objections, but really I'd like to see the isAtom() and isSLM() methods removed entirely - both appear to have been added as perf regression hacks over the years, and then reused where proper feature flags should have been added instead.
