Evgeniy Stepanov 1bc7298c44 [asan] Fix nonsensical reports of partial right OOB.
In case of partial right OOB, ASan was reporting
  X is located 0 bytes to the right of [A, B)
where X was actually inside [A, B).

With this change, ASan will report B as the error address in such case.

Alexander Potapenko cae42d23a6 [ASan] Use dylib interposition to hook memory allocation in the dynamic runtime.
This CL drastically simplifies the way we're hooking the memory allocation routines in ASan on Mac by using dylib interposition to replace the main malloc_zone_* functions. This allows us to avoid replacing the default CFAllocator and drop the CF dependency at all.

Committing this patch will result in the static runtime being broken. A follow-up CL will switch ASan to use the dynamic runtime library.

Alexey Samsonov ca7fcf2354 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.
