Protect compiler directives during mutation #3116

Open dupdob opened 4 days ago

dupdob commented 4 days ago

Ensure compiler directives (#if, #pragma....) are not mutated but kept around mutated syntax nodes.

This required small changes in every mutator, as they are not responsible for removing any directive. I took this as an opportunity to improve the design.

Also, added generation of semantic model during mutation tests to ensure mutator related unit tests are relevant. I may have fixed some minor issues on them.

Also added some top level statement in integration test as it was a quick win

FIxes #3081, #3102

I am happy to see this PR reduces the total number of lines, and it increases the number of mutations. This is probably related to the redesign of the pattern mutator that I modified so it no longer does some internal scan and reenabled orchestration of patterns in general
