To reproduce:

  1. go get github.com/google/go-cmp/cmp
  2. cd $GOPATH/src/github.com/google/go-cmp/cmp
  3. go test
# github.com/google/go-cmp/cmp_test
./compare_test.go:23:2: could not import github.com/google/go-cmp/cmp (cannot import, possibly version skew (embedded type is not an interface) - reinstall package)
./compare_test.go:481:23: cannot range over p (invalid operand)
vet: typecheck failures
FAIL	github.com/google/go-cmp/cmp [build failed]

Appears to be related to fix for #25301.

This is probably a duplicate of #25596.
