[Green Dragon's lldb incremental tests (x86_64)](https://green.lab.llvm.org/job/llvm.org/view/LLDB/job/lldb-cmake/) are failing beginning with https://github.com/llvm/llvm-project/pull/168611. This commit reverts that change. If the job continues to fail after committing this revert, then I will recommit the original. rdar://166741668 This reverts commit 6344e3aa8106dfdfb30cac36c8ca02bc4c52ce24.
