** Resolve names in expressions that can only reference a single table

**
**    (1)   CHECK constraints
**    (2)   WHERE clauses on partial indices
**    (3)   Expressions in indexes on expressions
**    (4)   Expression arguments to VACUUM INTO.
**
** In all cases except (4), the Expr.iTable value for Expr.op==TK_COLUMN
** nodes of the expression is set to -1 and the Expr.iColumn value is
** set to the column number.  In case (4), TK_COLUMN nodes cause an error.
**
** Any errors cause an error message to be set in pParse.
