Some IE11 updates and fixes to subtest name logging discrepancies.

In lieu of being able to produce all new IE results for a full test pass on the latest html suite (our in-house w-p-t automation is temporarily down), here are at least our last results (in html/test-results) with the subtest name logging discrepancies fixed and also results for new tests (run via W3C in-browser runner) added and deleted tests removed.

These changes seem to take care of ~1300 subtest failures on the less-than-2 report (at least using the version of less-than-2.js in html/test-results and the latest other browser results at test-results/html). Maybe these failures are already accounted for in the newly filtered less-than-2 report, but here is the update in case its useful.
