Teresa Johnson 611bafa4c4 Perform symbol binding for .symver versioned symbols ... Summary: In a .symver assembler directive like: .symver name, name2@@nodename "name2@@nodename" should get the same symbol binding as "name". While the ELF object writer is updating the symbol binding for .symver aliases before emitting the object file, not doing so when the module inline assembly is handled by the RecordStreamer is causing the wrong behavior in *LTO mode. E.g. when "name" is global, "name2@@nodename" must also be marked as global. Otherwise, the symbol is skipped when iterating over the LTO InputFile symbols (InputFile::Symbol::shouldSkip). So, for example, when performing any *LTO via the gold-plugin, the versioned symbol definition is not recorded by the plugin and passed back to the linker. If the object was in an archive, and there were no other symbols needed from that object, the object would not be included in the final link and references to the versioned symbol are undefined. The llvm-lto2 tests added will give an error about an unused symbol resolution without the fix.
