Chris Jenneisch 356e28fdb1 Use std::unordered_map for mTagToTypeMap 
In the profile we notice that  SortedVectorImpl::_indexOrderOf is
almost 1.6% which is quite high considering it is an access to
a container. We make mTagToNameMap as a std::unordered_map
to store the Tag and the types. The accesses would be in constant time.

This change removes this from the profile and give ~10% improvement.
