Andrey Konovalov 2e903b9147 kasan, arm64: implement HW_TAGS runtime 
Provide implementation of KASAN functions required for the hardware
tag-based mode.  Those include core functions for memory and pointer
tagging (tags_hw.c) and bug reporting (report_tags_hw.c).  Also adapt
common KASAN code to support the new mode.
