Rerun regression tests to clean up merge conflicts

Manually deleted one of the merge conflict files, msvc-2022-c++latest/pure2-type-safety-1.cpp.output

I don't see /gcc-10-c++20/mixed-type-safety-1.cpp.output, but /gcc-10-c++20/mixed-type-safety-1.cpp.execution somehow shows as updated but with "No content changes found" ... ?

Well, I'll commit this and see if it helps with the merge conflict... feel free to undo/overwrite if this isn't helpful...
