From: Andrey Konovalov <andreyknvl@xxxxxxxxxx>
Subject: kasan: add __asan_report_loadN/storeN_noabort callbacks
Instead of __asan_report_load_n_noabort and __asan_report_store_n_noabort
callbacks Clang emits differently named __asan_report_loadN_noabort and
__asan_report_storeN_noabort (similar to __asan_loadN/storeN_noabort,
whose names both GCC and Clang agree on).
Add callback implementation for __asan_report_loadN/storeN_noabort.
