Enable more tests on AArch64

[akirilov-arm]

These changes are partially in support of #2960. With them the tests run on AArch64 should be the same as those executing on x86-64, except for a couple that are specific to the latter platform, 3 that fail under QEMU, and some CLIF tests missing the target aarch64 directive.

Well, on the plus side all AArch64 tests pass (including the new additions), but now there is a macOS failure, even though my patch is not supposed to change anything for that platform (since it is not AArch64-based in CI).

@alexcrichton Any suggestions?

Oh that's ok, that's a known flaky test failure

OK, I started another run - hopefully it will pass this time.

This looks good to me now, as far as s390x is concerned. Thanks!
