Issue with demangling name from enum member

If the name from a enum member is a mangled name it will not be demangled

enum RS

{ RS_40NM, RS_60NM, RS_80NM}

;
enum class RSC

{ RSC_40NM, RSC_60NM, RSC_80NM}

;

RS nm;
RSC nmc;

int main(void)

{ nm = RS_40NM; nmc = RSC::RSC_40NM; return 0; }

In the expressions view nm is displayed as RS_40NM while nmc is mangled
