In the failed build, there are two tests not run: `crashop-reduction.mlir` and `multiple-function.mlir`. However, the problem was unable to reproduce locally on these tests as well as on whole `check-mlir` target: all tests are passed. This is also strange, as tests are failed on CI for PowerPC, while commit is made in AArch64 back-end.

Finally, next CI [job](https://lab.llvm.org/buildbot/#/builders/129/builds/38527) on subsequent commit passes.
So, this probably might be a CI environment problem.
