[release-branch.go1.18] go/types, types2: pointer base types cannot be type constraints
Pointer types may appear in expressions *P and we don't know if
we have an indirection (P is a pointer value) or a pointer type
(P is a type) until we type-check P. Don't forget to check that
a type P must be an ordinary (not a constraint) type in this
special case.
Fixes #51578.
