This does not segregate between "we haven't found the bitstream in the COFF
object" vs. "there's an error while parsing the object". If the return code is
`object_error::bitcode_section_not_found` we should fallback on the
`ObjFile::create` case; whereas any other error should be emitted in the log
(`Fatal(ctx) << ...`)
