Chris Lattner f88dd5ed64 remove two trunc xforms that are subsumed by EvaluateInDifferentType. 
The only difference is that EvaluateInDifferentType checks to ensure
they are profitable before doing them :)

Benjamin Kramer ccce8bae14 Avoid going through the LLVMContext for type equality where it's safe to dereference the type pointer.

Chris Lattner 2b295a0eba split 943 lines of instcombine out to a new InstCombineCasts.cpp 
file.  InstructionCombining.cpp is now down to a svelte 9300 lines :)
