Series kasan: add hardware tag-based mode for arm64 | expand

Commit Message

Andrey Konovalov Oct. 29, 2020, 7:25 p.m. UTC 
This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.

The new mode won't be using shadow memory, so only build init.c that
contains shadow initialization code for software modes.

No functional changes for software modes.
