Very minor but easy optimization for symbol_scope_t
Lots of symbol_scope_t throwaway objects get created during value
expression calculation, and 99% of them are never used. Therefore, the
std::map which each contains is now within an optional<> wrapper, so
that no constructor happens unless one is actually used.
