No changes to the values. However, to avoid noise with every bugfix
release changing all the lines, only use go1.X rather than go1.X.Y
to annotate each of the entries in maps and lists.
This lets us start taking advantage of featurs from Go 1.23,
particularly tracking aliases in go/types and iterators.
Note that we need to add code to properly handle or skip over the new
*types.Alias type which go/types produces for Go type aliases.
Also note that we actually turn this mode off entirely for now,
due to the bug reported at https://go.dev/issue/70394.
We don't yet remove our own alias tracking code yet due to the above.
We hope to be able to remove it very soon.
This teaches the program how to collect information from multiple
Go versions and join it together. For this to work, it needs to
select the Go versions itself, which is now possible via GOTOOLCHAIN.
The merging of data is fairly simple; we join the results from all
versions, and we remove duplicates from older Go versions.
Start producing output with the Go version noted on every data point,
so that we can easily scan what each Go version is contributing.
