Subject: Add soft-float to the key for the subtarget lookup in the
 TargetMachine map, this makes sure that we can compile the same code for two
 different ABIs (hard and soft float) in the same module.

Update one testcase accordingly (and fix some confusing naming) and
add a new testcase as well with the ordering swapped which would
highlight the problem.
