This implements another previously undocumented part of the D ABI spec, where symbols with no name are always encoded into the mangled name.
SymbolName: LName TemplateInstanceName 0 // anonymous symbols This has never really been a problem, as strtol() kindly jumps over any leading zeros in the number it is parsing. However this change makes it so they are at least explicitly skipped over, rather than silently ignored. ---
