With latest PR #13718

I can see some SLT tests are taking forever on Windows

Executed "map.slt". Took 460.5636141s
Executed "window.slt". Took 217.240136s
Executed "struct.slt". Took 1316.049712s
Executed "array.slt". Took 2407.7054095s

Which probably relates to different optimizations needed to apply for Windows platform comparing to unix/macos

The compilation is 13 mins for main DF and for CLI so 26mins in total comparing to 10mins in macos/unix, but the biggest problem for now is test run time which is probably related to different set of optimizations Windows expects
