Previously, it was ambiguous whether `BlockNode::iter_vars` were in-scope for `BlockRealizeNode::predicate`. `ConvertBlocksToOpaque` treated them as in-scope, and applied a mapping from `iter_vars` to `iter_values`. Similarly, TVMScript printing places `T.where` statements below the `T.axis` statements, where `T.axis` definitions are in scope. However, `BlockRealizeNode::SEqualReduce` and `BlockRealizeNode::SHashReduce` do not visit the block and `iter_vars` until after visiting the predicate, placing the `iter_vars` out of scope. This commit updates the printing of `T.where` to be above `T.axis`, and updates `ConvertBlocksToOpaque` to report an error if the predicate contains references to `BlockNode::iter_vars`. After this commit, these three usages all consistently treat `BlockNode::iter_vars` as out of scope for `BlockRealizeNode::predicate`. -- This is an automated message from the Apache Git Service.
