[nicolasstucki]

Add AST nodes for Quote, Splice, QuotePattern, and QuoteSplice to TASTy.

Term          = 
                  ...
                  QUOTE          Length body_Term bodyTpe_Type                     -- Quoted expression `'{ body }` of a body typed as `bodyTpe`
                  SPLICE         Length expr_Term tpe_Type                         -- Spliced expression `${ expr }` typed as `tpe`
                  SPLICEPATTEN   Length pat_Term tpe_Type targs_Type* args_Term*   -- Pattern splice `${pat}` or `$pat[targs*](args*)` in a quoted pattern of type `tpe`.

@WojciechMazur could you test this PR on the open community build?

[WojciechMazur]

The OpenCB was started, I'll post the result tomorrow when it's done

We have 4 projects that started to fail after this change. In most cases it seems like the typer issue, eg.

Error:     |           Found:    Int => String
Error:     |           Required: T => Any

Does this TODO need to be addressed now? If not, how can we do it backward-compatibly in the future?

[nicolasstucki]

I previously thought that we could do it in a backward-compatible way, but now I see that my strategy will not work. I will propose another solution that will be future-proof for #18271.

[nicolasstucki]

Actually my original idea will work. I replaced the comments with a partial implementation.

I fixed these with the change in 3f2db24. This also removed the changes in the checkfiles (these where suspicious).

This has been decided to be included in the 3.5.0 release.
