Daniel Dunbar a54a1b0edf ARM/Thumb2: Fix a misselect in getARMCmp, when attempting to adjust a signed 
comparison that would overflow.
 - The other under/overflow cases can't actually happen because the immediates
   which would trigger them are legal (so we don't enter this code), but
   adjusted the style to make it clear the transform is always valid.

Chris Lattner 9ef94277f1 adjust for signedness change. I'd appreciate it if an ARM flavored person 
could look at this: the top undefined bits of an immediate shouldn't affect
isel (cmp vs cmp.w)
