[PATCH 0/2] KASan for arm64

[Andrey Ryabinin <a.ryabinin@samsung.com>]

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.
