Tobias Tebbi 4f48d04f97 [turbofan] introduce a deterministic tick measurement and assert optimization doesn't take too long ... This adds a simple counter to Turbofan that's incremented throughout the compilation, hopefully frequently enough so we can use it to detect divergence and performance bugs. In addition, we assert that this counter never gets too high. That's the equivalent of a simple timeout, just more deterministic. The limitations on Turbofan input size should guarantee that we never exceed this limit. Since we probably do exceed it rarely, this check is only a DCHECK and intended to detect performance and divergence issues, but not supposed to be performed in release builds. In addition, this CL adds UMA stats to observe the real world distribution of the tick measurement.
