Log Message:
Move the MI parts of KASAN into kern/subr_asan.c. This file includes
machine/asan.h, which contains the MD functions. We use an include rather
than a plain C file, because we want GCC to optimize/inline some functions
into one single block.

The amd64 MD parts of KASAN are moved accordingly.

The naming convention we use is:

        kasan_*
                a generic kasan object, declared in subr_asan.c
        kasan_md_*
                an MD kasan object, declared in machine/asan.h, and used
                in subr_asan.c
        __md_*
                an MD object, declared in machine/asan.h, and not used
                outside

Overall this makes it easier to add KASAN support on more architectures.

Discussed with several people.
