Reynold Xin 3ba34d435c [SPARK-14990][SQL] Fix checkForSameTypeInputExpr (ignore nullability) ... ## What changes were proposed in this pull request? This patch fixes a bug in TypeUtils.checkForSameTypeInputExpr. Previously the code was testing on strict equality, which does not taking nullability into account. This is based on https://github.com/apache/spark/pull/12768. This patch fixed a bug there (with empty expression) and added a test case. ## How was this patch tested? Added a new test suite and test case. Closes #12768.
