Debug Info: Support for DW_AT_export_symbols for anonymous structs
This implements the DWARF 5 feature described in:
http://dwarfstd.org/ShowIssue.php?issue=141212.1
To support recognizing anonymous structs:
struct A {
struct { // Anonymous struct
int y;
};
} a;
This patch adds a new (DI)flag to LLVM metadata:
ExportSymbols
