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.

It is possible for ReExec to be called before the C standard library
has initialised itself sufficiently for execv to work properly.
Fix this by parsing the environment ourselves and using execve.
