  Changed paths:
    M llvm/include/llvm/Support/Parallel.h
    M llvm/lib/Support/Parallel.cpp

  Log Message:
  -----------
  [Support] Simplify parallelForEach{,N}

* Merge parallel_for_each into parallelForEach (this removes 1 `Fn(...)` call)
* Change parallelForEach to use parallelForEachN
* Move parallelForEachN into Parallel.cpp

My x86-64 `lld` executable is 100KiB smaller.
No noticeable difference in performance.
