This predicate was slow, mostly because it's just very large. A manual
join order cuts the run time on Chromium from
definitions::Top::hasLocationInfo_dispred#ffffff ..................... 3m23s
definitions::MacroAccessWithHasLocationInfo::hasLocationInfo#ffffff .. 1m56s
to
definitions::Top::hasLocationInfo#ffffff .... 2m28s
The main slowdown was the two uses of `SCAN` to reorder columns in the
RA.
