Summary: Conflicting types for the same section name defined in clang section pragmas and GNU-style section attributes were not properly captured by Clang's Sema. The lack of diagnostics was caused by the fact the section specification coming from attributes was handled by Sema as implicit, even though explicitly defined by the user. This patch enables the diagnostics for section type conflicts between those specifications by making sure sections defined in section attributes are correctly handled as explicit.
