  Changed paths:
    M llvm/include/llvm/Support/InstructionCost.h
    M llvm/unittests/Support/InstructionCostTest.cpp

  Log Message:
  -----------
  Reland "Ensure that InstructionCost actually implements a total ordering"

The operator< in the previous attempt was incorrect. It is unfortunate
that this was only caught by the expensive checks.

This reverts commit ff1147c3635685ba6aefbdc9394300adb5404595.
