Make sure that both variants of the nasty TF-in-compat-syscall are exercised regardless of what vendor's CPU is running the tests. Also change the intentional signal after SYSCALL to use ud2, which is a lot more comprehensible. This crashes the kernel due to an FSGSBASE bug right now. This test *also* detects a bug in KVM when run on an Intel host. KVM people, feel free to use it to help debug. There's a bunch of code in this test to warn instead of going into an infinite looping when the bug gets triggered.
