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.

# Unfortunately, due to https://go.dev/issue/22315, cp + exec is racy.
|
|
# Since we run multiple test scripts in parallel as goroutines,
|
|
# if one thread performs a cp while another is forking, the other may keep the
|
|
# file open slightly longer than we think, causing the fork to fail due to the
|
|
# file still being open for writing.

# Until the root problem is fixed, add a sleep to try to make that narrow window

# of time less likely to cause problems.
