  Changed paths:
    M llvm/include/llvm/ADT/DenseMapInfo.h
    M llvm/include/llvm/Support/TypeSize.h

  Log Message:
  -----------
  Move DenseMapInfo traits to TypeSize.h

Saves 2427 unneeded includes of TypeSize.h, which instantiates
std::tie<uint64_t, bool>, which instantiates std::tuple<uint64_t, bool>,
which is slow.

I'll remove the tie in a follow-up, since it's just for operator==.
