The default s390x cpu(z10) does not have vector support. Setting target-cpu at least to z13 enables vectorisation for s390x architecture and makes the tests pass.

…Mark-Simulacrum Use -C target-cpu=z13 on s390x vector test currently we see a regression in the `dont-shuffle-bswaps.rs` on s390x. This is due to, the default s390x cpu is set to z10 [here](https://github.com/rust-lang/rust/blob/master/compiler/rustc_target/src/spec/targets/s390x_unknown_linux_gnu.rs#L9) which does not have vector instructions implemented. To make the test pass we need to create an extra test revision and set target-cpu at least to `z13`.

currently we see a regression in the
dont-shuffle-bswaps.rson s390x. This is due to, the default s390x cpu is set to z10 here which does not have vector instructions implemented. To make the test pass we need to create an extra test revision and set target-cpu at least toz13.
