KCOV is code coverage collection facility used, in particular, by syzkaller system call fuzzer. There is some interest in using syzkaller on arm devices. So port KCOV to arm. On implementation level this merely declares that KCOV is supported and disables instrumentation of 3 special cases. Reasons for disabling are commented in code. Tested with qemu-system-arm/vexpress-a15.
