[modules] Detect and throw exceptions for cyclic dependencies Use an unordered_map<Module, unordered_set<String>> to keep track of visited Module/ExportName pairs during ResolveExport. This required adding a Hash() method to Module, which is accomplished by allocating a Symbol and storing it in the SharedFunctionInfo::name slot, then delegating the hash to that Symbol. Also added a helper method Module::shared() to easily get ahold of the SharedFunctionInfo and call it in the appropriate places instead of re-doing the ternary operator.
