On the one hand, one might interpret the use of the max-token pragmas or -fmax-tokens flag as an opt-in to the warning. However, in Chromium we've found it useful to only opt in selected build configurations, even though we have the pragmas in the code. For that reason, we think it makes sense to turn it off by default. Differential revision: https://reviews.llvm.org/D80014
