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.

[asan] asan_allocator2: improve FindHeapChunkByAddress to find memory chunks to the left of a given address. Almost all tests pass with the new allocator now, only 6 are left to fix.

[asan] extend overflow-in-qsort.cc to check both unwind kinds. One more test for SlowUnwind. Move both to Linux dir (no slow unwind on Mac)

[asan] add two asan flags: fast_unwind_on_fatal and fast_unwind_on_malloc to allow using the slow CFI-based unwinder

[Sanitizer] Add new header - sanitizer_platform_interceptors.h, which should define whether or not given function should be intercepted on a given platform.

[sanitizer] replace size_t with SIZE_T in interceptors (same for ssize_t, off_t and off64_t). This is done to avoid confusion and to make the code work with compilers that define size_t w/o any includes (MSVC)
