Use the predicate condition instead of checkFeatures in *GenDAGISel.inc.

This makes the code similar to isel pattern predicates.

checkFeatures is still used by code created by SubtargetEmitter so
we can't remove the string. So backends need to be careful to keep
the string and predicates in sync, but I don't that's a big issue.

I haven't measured it, but this should be a compile time improvement
for isel since we don't have to do any of the string processing that's
inside checkFeatures.
