  Changed paths:
    M llvm/include/llvm/IR/ModuleSummaryIndex.h
    M llvm/lib/LTO/LTO.cpp
    A llvm/test/ThinLTO/X86/cache-decoupled-from-filenames.ll

  Log Message:
  -----------
  [ThinLTO] Make the cache key independent of the module identifier paths

Otherwise there are cache misses just from changing the name of a path, even though the input modules did not change.
