Just a small note on this, tramp3d-v4 has consistently been an outlier in optimized debug build times; for essentially every change we've made regarding debug intrinsics, it has shown a several-times-larger increase than other projects, seemingly because it simply generates far more intrinsics than other llvm-test-suite projects. So, I _suspect_ the difference here is not due to any pathological input, but it's still a good project to use for benchmarking in any case.
