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.

The runtime skips atexit sleep if there are no threads now,
so it must be fast w/o it.
Allows to specify own TSAN_OPTIONS for the tests.

strictly best-effort; reading these bytes to display the note could lead to a
seg fault, and that's explicitly OK.

a file and line number if we have an external symbolizer.
