Log:
[debuginfo-tests] Support moving debuginfo-tests to llvm/projects
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.
