x/tools/gopls: strange error in type checking

[adonovan]

This was reported in #60551 (comment), but I think is a separate bug (in the ordinary type checking, not analysis component:

2023/06/13 10:49:34 computing the shared import graph: import failed for "vendor/golang.org/x/crypto/chacha20poly1305": internal error while importing "vendor/golang.org/x/crypto/chacha20poly1305" (conflicting names chacha20poly1305 and server for package "vendor/golang.org/x/crypto/chacha20poly1305"); please report an issue

I wonder whether we're making spurious hits in an ID or PackagePath-keyed import map because the current package is called "command-line-arguments"?
