Add Map core edition

[AdamGS]

Rationale for this change

New version that includes the map array and some testing changes around that.

Not sure what's our process for new editions is, but figured I'll at least put this up. Should the array not be in the default session until then? How do we manage this process?

Footnotes

1. 43 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on develop (12f7fea) during the generation of this report, so c8dc903 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
