ARM: Add KASan support
This adds KASan support to the ARM architecture. What we are doing is:
* Add __no_sanitize_address attribute to various lowlevel functions
which do not run in a proper C environment
* Add non-instrumented variants of memset/memcpy (prefixed with '__')
* make original memcpy/memset weak symbols so strong definitions in
lib/kasan/common.c can replace them
* Use non-instrumented memcpy in early functions
* call kasan_init()
