* passes: opt_share: don't statically initialize mergeable_type_mapSean Cross2019-09-091-3/+4
| | | | | | | | | | | | In 3d3779b0376b8204ed7637053176a07b7271ac1d this got turned from a `std::map<std::string, std::string>` to `std::map<IdString, IdString>`. Consequently, this exposed some initialization sequencing issues (#1361). Only initialize the map when it's first used, to avoid these static issues. This fixes #1361.
