[fpc-pascal] Constants in generics tests

[Ryan Joseph]

I made one final commit and now I’m submitting a patch for review. I’ve probably made mistakes in the patch process but I want to get this into the pipeline so it’s not just sitting there wasting space on my computer. Tests are included now and the link to the source on git is included in the report.
