Right, so IIUC the plan is to replace the single whole-file block `_LIBCPP_(BEGIN|END)_EXPLICIT_ABI_ANNOTATIONS` with one or more relatively small blocks, removing the `_LIBCPP_HIDE_FROM_ABI` from the rest of the file?

For SLoc usage, I use `-Xclang -print-stats` and look at Source Manager stats: https://github.com/llvm/llvm-project/blob/ea1d7e394e5fae100f0b703c3d61e01c0b0994cd/clang/lib/Basic/SourceManager.cpp#L2115-L2127
