Subject: [PATCH 1/2] [CI] Run LLDB tests on Clang changes in pre-merge CI

This attempts https://github.com/llvm/llvm-project/issues/132795 again.
Last time we tried this we didn't have enough infra capacity, so had to
revert. According to recent communication from the Infrastructure Area
Team, we should now have enough capacity to re-enable the LLDB tests.
