Is this an important difference?

When I added these, I hadn't realized that the current ASAN and MSAN bots are
Debug but the TSAN bot is Release. I had copy-and-pasted TSAN for ASAN and MSAN.

There will definitely be a difference, because Debug will enable code/asserts
that might not be XSAN-clean. I don't know how important that is.

My preference is that we don't introduce more differences between the current
bot and the new bot.

Agreed.
