Hover/go to definition do not work with top-level splices

[mpickering]

If you have a top-level splice then when you hover over it you get information about the generated code rather than the source program. I made a start at fixing this on a branch but got stuck working out how to mix together the splice expressions and the normal HieASTs information.

The plan for fixing this was:

• Add a hook to capture the spliced expression before it is run (implemented)
• Use this information in the GetHieFile rule in order to add information about the splice expression so it works with hover. (Where I am stuck)

I don't think enough stuff from HieAst is exported to implement this. Only enrichHie and mkHieFile are exported.

Working patch is on this branch: https://github.com/mpickering/ghcide/tree/wip/top-level-splices-hover

I only tested it with GHC 8.8.

Are you going to make a PR for this?

This should had been fixed by #759 which included https://github.com/mpickering/ghcide/tree/wip/top-level-splices-hover
Thanks!
