I believe I used this (by hacking up the gn files) locally on mac a while ago, but I'm not sure. LG, I'll try asan on mac and relax the assert if it works.

Naming-wise, it's maybe unclear if `use_?san` turns on the sanitizer for building llvm itself or for the output of clang or what, but it's consistent with the existing `is_clang` so maybe let's not worry about this too much for now.
