The config option for this changed in
https://secure.phabricator.com/D21313 (or when that was rolled out).
I'm leaving the old config option, which may be in use by people with
older versions of arc.

When you run `arc diff`, arc defaults to uploading all the changes you
have against the upstream branch into a single patch. This is almost
never what you want for stacked commits (patch series); you only want to
submit the changes done by the current patch. It's also come up as a
point of confusion in the Phabricator vs. GitHub PRs discussion, for
example. Configure arc to only upload your current patch by default,
which I think is a much more suitable default for LLVM developers.

conduit_uri was renamed to phabricator.uri and git-phab fails to load
.arcconfig without this field.

Summary:
Add cmake and lit files needed to run these tests as an
external project.  Also, copy test_debuginfo.pl from llvm/utils since
it's only used here.  The copy in llvm/utils must be maintained as
long as bots continue to include debuginfo-tests in clang/test.

This patch depends on clang patch https://reviews.llvm.org/D41055.
