Fangrui Song b3b970744d [ThinLTO] Add Visibility bits to GlobalValueSummary::GVFlags ... Imported functions and variable get the visibility from the module supplying the definition. However, non-imported definitions do not get the visibility from (ELF) the most constraining visibility among all modules (Mach-O) the visibility of the prevailing definition. This patch * adds visibility bits to GlobalValueSummary::GVFlags * computes the result visibility and propagates it to all definitions Protected/hidden can imply dso_local which can enable some optimizations (this is stronger than GVFlags::DSOLocal because the implied dso_local can be leveraged for ELF -shared while default visibility dso_local has to be cleared for ELF -shared). Note: we don't have summaries for declarations, so for ELF if a declaration has the most constraining visibility, the result visibility may not be that one.
