This CL pushes the typecheck.Expr calls further down to the IR construction points. It turns out we don't really care about typecheck.AssignExpr, because it's only used to distinguish whether ir.BlankNode is allowed. We can avoid that issue by just skipping the call to typecheck.Expr for blank nodes. Similarly, for typecheck.Callee, only two details matter: (1) don't report errors for builtin functions (which aren't allowed outside of callee contexts); and (2) method-value selector expressions need to have Op ODOTMETH/ODOTINTER rather than OMETHVALUE. The first can be handled by simply skipping typecheck on Names (as with ir.BlankNode, we don't need to typecheck these). The second currently requires adding a 'callee bool' parameter to disambiguate the context. The other option would be for exprCall to reset the fun's Op from OMETHVALUE to OXDOT and let typecheck handle it a second time. But I anticipate needing to add extra logic in the exprSelector case which would be harder to undo, so this seems somewhat better.
