Vitaly Buka c1e94591bc Revert "[asan] Enable detect_stack_use_after_return=1 by default" 
Temporarily revert the option to fix
https://bugs.chromium.org/p/chromium/issues/detail?id=1319387

This reverts option default and documentation of the commit. Test
changes are not being reverted as they are improvement and break
reliance on option defaults.

Additional memory usage is a problem on mobile devices with low memory.
Even heavy thread desktop programs may need some FakeStack tunning.

This reverts commit 4b4437c084e2b8a2643e97e7aef125c438635a4d.

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
