Clean up grammar's handling of NULL in expressions: a_expr_or_null is
gone, replaced by plain a_expr. The few places where we needed to
distinguish NULL from a_expr are now handled by tests inside the actions
rather than by separate productions. This allows us to accept queries
like 'SELECT 1 + NULL' without requiring parentheses around the NULL.
