When -ObjC is passed, the linker must force load any object files that contain special sections that store Objective-C / Swift information that is used at runtime. This should work regadless if input files are bitcode or native, but it was not working with bitcode. This is because the sections that identify an object file that should be loaded were inconsistent when dealing with a native file vs bitcode file. In particular, bitcode files were not searched for `__TEXT,__swift` prefixed sections, while native files were. This means LLD wasn't loading certain bitcode files and forcing the user to introduce --force-load to their linker invocation for that archive. Co-authored-by: Nuri Amari <nuriamari@fb.com>
