Crash with unnamed subquery in FROM

[Jille]

Version

1.25.0

What happened?

Queries like SELECT blah FROM (SELECT 1 AS blah); crash sqlc generate.

Changing it to SELECT blah FROM (SELECT 1 AS blah) t1; works as expected.

Relevant log output

panic: runtime error: invalid memory address or nil pointer dereference
