Chandler Carruth 28c1b294b8 Fix a bug in the readdir_r interceptor: when we reach the end of the 
directory stream, the entry is not written to, instead *result is set to
NULL and the entry is not written to at all.

I'm still somewhat suspicious of the correct instrumention here --
I feel like it should be marking the written range as the pointer in
*result and the length (*result)->d_reclen in case the implementation
decides not to use the passed-in entry (if that's even allowed).
Finally, the definition of 'struct dirent' analog used in the
interceptor is wrong in 32-bit mode with _FILE_OFFSET_BITS=64 as it hard
codes the use of a pointer-sized offset.

I've added a somewhat goofy test for the bug I fixed via ASan --
suggestions on how to better test the interceptor logic itself welcome.

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (asan) run-time library.
We are in the process of integrating AddressSanitizer with LLVM, stay tuned.

Directory structre:
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 run-time lirbary.
scripts/*        : Helper scripts.
tests/*          : ASan unit tests.
lit_tests/*      : ASan output tests.

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

Currently ASan runtime can be built by both make and cmake build systems.
(see compiler-rt/make and files Makefile.mk for make-based build and
files CMakeLists.txt for cmake-based build).

ASan unit and output tests work only with cmake. You may run this
command from the root of your cmake build tree:

make check-asan
