[PATCH] clang-modernize: Introduce process-based parallelism

[Manuel Klimek]

  I'd really like something like this in Tooling, so it'd be available for other tools - since it's basically just forwarding tool calls to subprocesses that should be doable.

  I'm also fine with checking this in for clang-modernize first, though, and work on getting the design for Tooling right on the side without blocking clang-modernize...

----------------
Shouldn't that be decremented by the number of finished jobs?
