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. llvm-svn: 170541
