Ongoing changes to the protobuf build system broke the previous performance harness scripts.

I've rebuilt the C++ perf harness by using a CMake build script to build libprotobuf and the C++ harness together. This uses more of the protobuf build machinery than I'd like -- it could probably be simplified and made more robust.

This has some requirements:

  • A protobuf source checkout that has all the submodules
  • abseil and googletest libraries installed on the local system and findable by CMake (On Mac, brew install abseil googletest seems to suffice)

This reuses some cmake logic from the protobuf dir,
which isn't ideal, but at least CMake knows how to handle
abseil.  <whew!>

Note:  This now expects abseil and googletests to be
already installed on the local system.  A more ambitious
setup here could potentially avoid that.

Not sure if you want to look at #605 at the same time, or if there's enough changed it's already effectively resolved.

This resolves apple#605 -- the previous code would leave the
local tree in a very confusing state.  This is slower, but
checks out the comparison commit to a completely separate
directory with no relation to the local directory and also
arranges for it to be completely cleaned up at the end.

I changed the handling for comparison checkouts -- it should avoid #605 now, though I still need to do more testing.
