XFAIL test that's inappropriate for AArch64 ABI

Only some ABIs require the "signext" attribute on parameters. On most
platforms, however, it's a useful test so it's best not to limit it to some
random arbitrary platform.

+// AArch64 ABI actually requires the reverse of what this is testing: the callee
+// does any extensions and remaining bits are unspecified.

+// Technically this test wasn't written to test that feature, but it's a
+// valuable check nevertheless.
