Etienne Bergeron 7a1bafd6ae This patch attempts to primitive support for Win64 asan 
Some known issues are:

When "head" include instructions that involve branching, the "cut and paste" approach may break down in a way that function interception still work but calling back the original function does not work.
The jmp [rip -8] saves some bytes in the "head" but finding the safe zone of 0xCC is not implemented yet. So it may stomp on preceding codes.
The shadow offset is not working yet on Win64. More complexity maybe involved since there are some differences regarding virtual address space between Window 8 and Windows 8.1/10.

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (ASan) runtime library.

Directory structure:
README.txt       : This file.
Makefile.mk      : File for make-based build.
CMakeLists.txt   : File for cmake-based build.
asan_*.{cc,h}    : Sources of the asan runtime library.
scripts/*        : Helper scripts.
tests/*          : ASan unit tests.

Also ASan runtime needs the following libraries:
lib/interception/      : Machinery used to intercept function calls.
lib/sanitizer_common/  : Code shared between various sanitizers.

ASan runtime currently also embeds part of LeakSanitizer runtime for
leak detection (lib/lsan/lsan_common.{cc,h}).

ASan runtime can only be built by CMake. You can run ASan tests
from the root of your CMake build tree:

make check-asan
