After bytecodealliance#6850 was merged, the s390x back-end now always uses iilf instead of lhi to load negative constants, which is a small code size regression. Fix the isle predicate to get back lhi whenever possible.

Looks like a flaky test with wasi-sockets (cc @sunfishcode?) -- retrying the merge. |

Hmm, the socket test is failing again -- @sunfishcode would you mind taking a look at this test? The PR changes only s390x stuff so shouldn't affect a macOS/x86-64 execution. |
