Dan Liew 16c3883b98 [asan_symbolize] Workaround bug in old Python 2 versions. 
The change landed in r358657 broke some of the buildbots because they
use an older version of Python 2 that raises this error.

```
File "/Volumes/data/dev/llvm/upstream/master/src/projects/compiler-rt/lib/asan/scripts/asan_symbolize.py", line 509
  exec(f.read(), globals_space, None)
SyntaxError: unqualified exec is not allowed in function 'load_plugin_from_file' it contains a nested function with free variables
```

I can reproduce this problem when using Python 2.7.6.

To workaround this some indirection has been added to prevent the broken
(the line at fault would never be executed) SyntaxError error in old
Python versions from being raised.

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
