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.

Even though both are allowed in the style guide, it recommends to use 'using', as its syntax is more consistent with the rest of C++. This CL turns all typedefs in compiler code to 'using' declarations.

This is some initial cleanup to keep /src clean. The AccountingAllocator is actually exclusively used by zones and this common subfolder makes that more clear. BUG=v8:5409 Review-Url: https://codereview.chromium.org/2344143003 Cr-Commit-Position: refs/heads/master@{#39558}

We expect that the majority of malloc'd memory held by V8 is allocated in Zone objects. Introduce an Allocator class that is used by Zones to manage memory, and allows for querying the current usage.

Up until now we used int32_t for NodeId, but that was not ideal because negative values are invalid for NodeId and we use it as an array index for example in the NodeMarker class, where C++ compilers on x64 have to generate code that does proper sign extension for the indices, which is completely unnecessary.
