Moved most target specific InstCombine parts to their respective targets.
The largest left-over part in InstCombineCalls.cpp is the code shared between arm and aarch64. Is there a place where code for these targets is shared?

The gist of these changes is in the following files:

- llvm/include/llvm/Analysis/TargetTransformInfo.h
- llvm/include/llvm/Analysis/TargetTransformInfoImpl.h
- llvm/include/llvm/CodeGen/BasicTTIImpl.h
- llvm/include/llvm/Transforms/InstCombine/InstCombiner.h
- llvm/lib/Analysis/TargetTransformInfo.cpp
- llvm/lib/Transforms/InstCombine/InstCombineInternal.h
- llvm/lib/Transforms/InstCombine/InstructionCombining.cpp

The rest of the changes are moving about 3000 lines out from InstCombine to the targets and slightly adjust them for the new interface, there should be no other changes in there.
