This is a follow-up for r273544. The end goal is to get rid of the isSwift / isCortexXY / isWhatever methods. This commit also removes a command line flag that isn't used in any of the tests: check-vmlx-hazards. It can be replaced easily with the mattr mechanism, since this is now a subtarget feature. There is still some work left regarding FeatureExpandMLx. In the past MLx expansion was enabled for subtargets with hasVFP2(), until r129775 [1] switched from that to isCortexA9, without too much justification. In spite of that, the code performing MLx expansion still contains calls to isSwift/isLikeA9, although the results of those are pretty clear given that we're only enabling it for the A9. We should try to enable it for all targets that have FeatureHasVMLxHazards, as it seems to be closely related to that behaviour, and if that is possible try to clean up the MLx expansion pass from all calls to isWhatever. This will require some performance testing, so it will be done in another patch.
