Hi,

This adds KASan for arm64.
First patch is a small prep, all major changes in the second.

It was lightly tested in qemu.
I should get a real hardware quite soon to test this.

TODO:
Add more interceptors for memory accessing functions (memcmp, strlen, ...),
though this could be done later.

kasan, x86: move KASAN_SHADOW_OFFSET to the arch Kconfig
