Adrian Prantl 559c6e17cd Make nrvo-string test more robust.
This is a follow-up to r364466, but better implemented. Original
commit message still applies:

    The breakpoint locations were in places where clang doesn't actually
    emit a source location for and depend on the debugger's ability to
    move the breakpoint forward onto a line that is already in the
    function epilogue. In my testing older versions of LLDB fail to do
    that, so I'm modifying the test to force a break-able location by
    calling a noinline function.

Amy Huang 7fac5c8d94 Store a pointer to the return value in a static alloca and let the debugger use that
as the variable address for NRVO variables.

Adrian Prantl a0de3a8d0a Revert "Temporarily pin tests to DWARF v2 until a more recent version of LLDB"
This reverts commit 319790.

We worked around the bug in LLVM instead.

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.
