History
Chris Lattner 82781b938a Teach the grouper some simple tricks about looking contradictory 
predicates.  For example if we have:

Scope:
  CheckType i32
    ABC
  CheckType f32
    DEF
  CheckType i32
    GHI

Then we know that we can transform this into:
Scope:
  CheckType i32
    Scope
      ABC
      GHI
  CheckType f32
    DEF

This reorders the check for the 'GHI' predicate above
the check for the 'DEF' predidate.  However it is safe to do this
in this situation because we know that a node cannot have both an
i32 and f32 type.

We're now doing more factoring that the old isel did.
