[MLIR] Refactor Krnl Dialect and Krnl Dialect Lowering (#375)
* Store bounds as affine map attributes & check in test cases with generic printer * Upgrading MLIR MLIR is outdated on Buildbot, rebuilding a newer version. * work with new version of mlir * check-in parser tests * custom printer * nit * bug fix * enable custom asm printer test * enable custom asm printer test * more consistent variable naming * test max/min * variable naming scheme change to MLIR style * can lower krnl to llvm * kernel -> llvm * comments * bug fix * try fixing ci * fix ci * deactivate model test * fix lit test * nit * fix z buildbot
