Zachary Turner 79708b54f2 Re-revert "Refactor debuginfo-tests."
This is still breaking greendragon.

At this point I give up until someone can fix the greendragon
bots, and I will probably abandon this effort in favor of using
a private github repository.

Zachary Turner 8b6ef88e7e Resubmit "Refactor debuginfo-tests" again.
This was reverted due to the tests being run twice on some
build bots.  Each run had a slightly different configuration
due to the way in which it was being invoked.  This fixes
the problem (albeit in a somewhat hacky way).  Hopefully in
the future we can get rid of the workflow of running
debuginfo-tests as part of clang, and then this hack can
go away.

Zachary Turner b5c237ec3d Re-revert "Refactor debuginfo-tests"
This is still broken because it causes certain tests to be
run twice with slightly different configurations, which is
wrong in some cases.

You can observe this by running:

  ninja -nv check-all | grep debuginfo-tests

And seeing that it passes clang/test and clang/test/debuginfo-tests
to lit, which causes it to run debuginfo-tests twice.  The fix is
going to involve either:

  a) figuring out that we're running in this "deprecated" configuration,
     and then deleting the clang/test/debuginfo-tests path, which should
     cause it to behave identically to before, or:
  b) make lit smart enough that it doesn't descend into a sub-suite if
     that sub-suite already has a lit.cfg file.

Zachary Turner 5e420717a1 Resubmit "Refactor debuginfo-tests"
This was reverted due to some failures on specific darwin buildbots,
the issue being that the new lit configuration was not setting the
SDKROOT environment variable.  We've tested a fix locally and confirmed
that it works, so this patch resubmits everything with the fix
applied.

Zachary Turner faf04a09f6 Revert "Update test_debuginfo.pl script to point to new tree location."
This reverts the aforementioned patch and 2 subsequent follow-ups,
as some buildbots are still failing 2 tests because of it.
Investigation is ongoing into the cause of the failures.

Zachary Turner 0f2ce11df7 [debuginfo-tests] Make debuginfo-tests work in a standard configuration.
Previously, debuginfo-tests was expected to be checked out into
clang/test and then the tests would automatically run as part of
check-clang.  This is not a standard workflow for handling
external projects, and it brings with it some serious drawbacks
such as the inability to depend on things other than clang, which
we will need going forward.

The goal of this patch is to migrate towards a more standard
workflow.  To ease the transition for build bot maintainers,
this patch tries not to break the existing workflow, but instead
simply deprecate it to give maintainers a chance to update
the build infrastructure.

Adrian Prantl 7e8f2ae649 Add a testcase for variable-length arrays.
VLAs are special-cased in the frontend. This testcase ensures that the
contract between clang and llvm won't be accidentally broken by future
refactorings.
