The main motivation for upstreaming this is to make -fembed-bitcode behaves the same as Apple clang.
The section is just a marker for ld64 to tell the linker there is no bitcode available for this specific module because it is built from assembly. If ld64 sees this marker, it will pull the object file into the bitcode bundle, rather than error out and complaining about missing bitcode.

Repository:
  rC Clang
