llvm-symbolizer should "Just Work"

The users expect ASan to print understandable error logs without any additional env
or output filtering.
Can we hardcode the compiler path somewhere so that ASan looks it up for llvm-symbolizer
if the path hasn't been supplied via env?

Instead, we should defeat the symbolizer to make it in-process.

Please remind me, have we considered putting the symbolizer into a .so?

Loading a .so with the system loader after a memory error or SIGSEGV occurs seems dicey.
 Couldn't you be inside malloc or the loader?

If you ignore stacks from signal handlers, then maybe the problem is easier.  From
signal handlers, it seems like the symbolizer has to be careful to avoid malloc.
