arsenm added inline comments.


================
Comment at: lib/Analysis/ValueTracking.cpp:1028-1029
   case Instruction::IntToPtr:
   case Instruction::AddrSpaceCast: // Pointers could be different sizes.
     // Fall through and handle them the same as zext/trunc.
     LLVM_FALLTHROUGH;
----------------
AddrSpaceCast should probably just be removed from the switch
