Dion Moult 64805b409f ifcparse: store the GlobalId index in a hash map with inline keys ...

byguid_ was a std::map<std::string, ...>: a red-black node plus a
heap-allocated 22-character string per rooted instance, and a lookup that
walks ~18 levels of string comparisons on a 200k-entry file.

guid_map keeps keys of up to 23 characters inline in an unordered_map node
(every valid GlobalId is 22), and routes anything longer to an ordered map
so invalid files still work. Same std::string-keyed interface as before.
