…ion (#18567) Note this targets the branch-51 release branch ## Which issue does this PR close? - part of #17558 - resolves #17801 in the 51 release branch ## Rationale for this change - We merged some clever rewrites for `coalesce` and `nvl2` to use `CASE` which are faster and more correct (👏 @chenkovsky @kosiew ) - However, these rewrites cause subtle schema mismatches in some cases planning (b/c the CASE simplification nullability logic can't determine the correct nullability in some cases - see #17801) - @pepijnve has some heroic efforts to fix the schema mismatch in #17813 (comment), but it is non trivial and I am worried about merging it so close to the 51 release and introducing new edge cases ## What changes are included in this PR? 1. Revert #17357 / e5dcc8c 3. Revert #17991 / ea83c26 2. Revert #18191 / 22c4214 2. Cherry-pick 6202254, a test that reproduces the schema mismatch issue (from #18536) 3. Cherry-pick 735cacf, a fix for the benchmarks that regressed due to the revert (from #17833) 4. Update datafusion-testing (see separate PR here) for extended tests (see apache/datafusion-testing#15) ## Are these changes tested? Yes I added a new test ## Are there any user-facing changes? <!-- If there are user-facing changes then we may require documentation to be updated before approving the PR. --> <!-- If there are any breaking changes to public APIs, please add the `api change` label. -->
