I can read D140478 <https://reviews.llvm.org/D140478> more closely, but I think D140478 <https://reviews.llvm.org/D140478> and this patch are different.

For `.debug_line` and `.debug_frame` special handling, we really just want to get rid of the legacy "fast path" (faster for assembling but  slow for direct machine code emission, added circa 2010 or before).
