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.

This hoists most of the CFLAGS into a common variable. It also adds
detection for -Wno-c99-extensions and uses it to silence a pile of
warnings.
Finally, it switches to the proper flag -rdynamic.
With this, the cmake build is warning free on my bootstrap Linux build.

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.

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.
