Significantly change the way we build ASan unittests in CMake
...
build tree. Now just-built Clang is used to:
1) compile instrumented sources (as before);
2) compile non-instrumented sources;
3) compile our own instrumented version of googletest;
4) link it all together using -fsanitize=address flag
(instead of trying to copy linker behavior in
CMake build rules).
This makes ASan unittests pretty much self-consistent
and independent of other LLVM libraries.

Relocate the external headers provided by ASan and the common sanitizer
...
library.
These headers are intended to be available to user code when built with
AddressSanitizer (or one of the other sanitizer's in the future) to
interface with the runtime library. As such, they form stable external
C interfaces, and the headers shouldn't be located within the
implementation.
I've pulled them out into what seem like fairly obvious locations and
names, but I'm wide open to further bikeshedding of these names and
locations.
I've updated the code and the build system to cope with the new
locations, both CMake and Makefile. Please let me know if this breaks
anyone's build.
The eventual goal is to install these headers along side the Clang
builtin headers when we build the ASan runtime and install it. My
current thinking is to locate them at:
<prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h
<prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h
<prefix>/lib/clang/X.Y/include/sanitizer/...
But maybe others have different suggestions?
Fixing the style of the #include between these headers at least unblocks
experimentation with installing them as they now should work when
installed in these locations.

This hoists most of the CFLAGS into a common variable. It also adds

Add support for building the ASan instrumentation unit tests with the
...
just-built Clang binary, and linking them against the just-built ASan
runtime.
This is *very* brittle. I expect it will require tweaking, and I've
pro-actively disabled it on non-Unix builds and on cross-builds.
It is also currently missing dependency edges on GoogleTest header files
and a few other corner cases, but those can be fixed. This is the major
milestone of a mini-bootstrap-like build of the unittest.

Cleanup the handling of CFLAGS even more in the cmake build for ASan.
...
Add the initial support for building ASan tests.
The first change here is to try to get the CFLAGS to more closely match
those used by the old Makefile. There are probably still goofs here,
ASan folks, your review would be appreciated.
The second big change is to add support for building both
instrumentation based an non-instrumentation based unittests for ASan.
They are built a bit differently from how the old makefiles managed
things. Specifically, there are two binaries, one for the
non-instrumented case, and one for the instrumented case.
Also, the instrumented unit tests rely on the host compiler supporting
AddressSanitizer's intrumentation pass. This is kind-of gross, but
I don't know of a better way yet. I've mailed llvmdev to discuss this
issue.
One big caveat is that the detection logic currently doesn't work. I've
commented it out temporarily as I'd like to get feedback from the ASan
developers, etc.

Actually intercept free() to ensure that the deallocations caused by other functions directly calling it are routed to our allocator.
...
For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.
