Revert "Don't build invalid AST nodes during recovery"

This reverts commit r224451. It caused us to reject some valid existing
code.

This code appears to run in non-error cases as well as error cases. If
the scope of a DependentScopeDeclRefExpr is still incomplete it probably
means we still have more instantiation to do.
