  Changed paths:
    M llvm/lib/Transforms/Coroutines/CoroFrame.cpp
    M llvm/lib/Transforms/Coroutines/CoroInternal.h
    M llvm/lib/Transforms/Coroutines/CoroSplit.cpp
    M llvm/test/Transforms/Coroutines/coro-debug.ll

  Log Message:
  -----------
  Better document the limitations of coro::salvageDebugInfo()

and fix a few edge cases that show up in the Swift compiler but
weren't caught by the existing tests. Most notably the old code wasn't
salvaging load operations correctly. The patch also gets rid of the
LoadFromFramePtr argument and replaces it with a more generalized
mechanism.
