This is a follow-up for r273544.
    
The end goal is to get rid of the isSwift / isCortexXY / isWhatever methods.
    
This commit also removes two command-line flags that weren't used in any of the
tests: widen-vmovs and swift-partial-update-clearance. The former may be easily
replaced with the mattr mechanism, but the latter may not (as it is a subtarget
property, and not a proper feature). If anyone needs to control that from the
command line, please speak now (and help me add a test).
