1. [5.5][clang][Driver] Make multiarch output file basenames reproducible …

   When building a multiarch MachO binary, previously the intermediate
   output file names would contain random characters. On macOS this
   filename, since it's used when linking, ended up being used as a
   stable-ish identifier for the adhoc codesignature of the binary, leading
   to non-reproducible binaries. This change uses the architecture, when
   available, to create a stable, but unique, basename for the file.
   
   Differential Revision: https://reviews.llvm.org/D111269
   
   This fixes FB9727658 (although the linker should still probably be
   updated to fix other related use cases)
   
   (cherry picked from commit 17386cb)
