Another big step toward a viable CMake build system for CompilerRT, ASan, and friends. This explicitly switches the CompilerRT CMake build to require CMake version 2.8.8 or newer which provides first-class support for "object" libraries which consist of a pile of '.o' files -- exactly what is desired for composing runtime libraries. I've gone ahead and switched to using this. I've also added the interception library which I missed initially. And I've added proper dependencies between the various libraries. With this, I'm able to build archives for asan that appear to contain all of the necessary .o files. The final tweak here is to start setting up the compile flags and macro defines expected by ASan and its helper libraries. These may not be entirely correct currently, they're based loosely on my reading of the old Makefiles. However, they can be tweaked more easily now that they're wired up properly. llvm-svn: 159129

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. llvm-svn: 159134
