r342003 added support for emitting FPO data from the DEBUG_S_FRAMEDATA subsection of the .debug$S section to the PDB file. However, that is not the end of the story. FPO can end up in two different destinations in a PDB, each corresponding to a different FPO data source. The case handled by r342003 involves copying data from the DEBUG_S_FRAMEDATA subsection of the .debug$S section to the "New FPO" stream in the PDB, which is then referred to by the DBI stream. The case handled by this patch involves copying records from the .debug$F section of an object file to the "FPO" stream (or perhaps more aptly, the "Old FPO" stream) in the PDB file, which is also referred to by the DBI stream. The formats are largely similar, and the difference is mostly only visible in masm generated object files, such as some of the low-level CRT object files like memcpy. MASM doesn't appear to support writing the DEBUG_S_FRAMEDATA subsection, and instead just writes these records to the .debug$F section. Although clang-cl does not emit a .debug$F section ever, lld still needs to support it so we have good debugging for CRT functions.
