CFI is a clang-specific feature that depends on LTO. Based on the earlier
LTO discussion, we decided to collect some more evidence that clang's LTO
doesn't actually break anything in the kernel before sending out the next
revision of these patches. I will look into upstreaming this code again
once we have sufficient test coverage, hopefully by the end of the year.
