I'm not seeing why it wouldn't work w/ `%t` as the directory? I'd think that `hwasan_symbolize --symbols %t --index` would work just as well, right? same w/ the `%run` bits.

There's also always `cd` if you need things in the CWD. Downside is that you can't just copy paste commands from lit anymore w/o using `cd`  yourself, but I know LLD tests use this pattern frequently.

While its deprecated there is also `%T`. That has issues w/ races though, so even then I'm not terribly sure you want to use it, but you don't need `$(dirname %t)` calls throughout.
