At the moment, the isolate is allocated and initialized in a single step. This has the downside that the platform cannot register the isolate before the isolate gets initialized, and therefore the platform is not available for the isolate during initialization. With this CL we register the uninitialized isolate on the platform and initialize the isolate after that. This change is needed to allow the creation of task runners already during the initialization of the isolate.

When attributing ticks to a function, we first check if the current pc matches a section within the dynamic library. If we find a match here, then we don't continue looking within dynamically generated range information, e.g. for JS functions and builtins. This logic breaks when embedded builtins come into play. They live within the libv8.so shared library, and are found when looking up statics. But what we really want is to look up the dynamically generated code-range, which contains more precise information. In this CL, this case is detected by matching the found symbol name. If it's the embedded blob, then we continue to dynamic lookup.

This CL introduces an stack abstraction for writing frame descriptions. Previously, we managed the output offset by hand, which is verbose and error prone. This CL introduced FrameWriter, which offers a stack abstraction with push operations for constructing the output frame descriptions. The abstraction is only applied to DoComputeBuiltinContinuation; following CLs will apply it to the other DoCompute* functions.

Instead of passing multiple pointers to input and output, or to two input values, just pass one pointer which holds all inputs and where the output is written. This also reduces the size of generated Turbofan graphs, since only one stack slot is needed and less arguments are passed to the call. It also fixes undefined behaviour, since we were passing a pointer e.g. as {uint64_t*}, but accessed it using {ReadUnalignedValue}. Now we pass an Address, which does not have any alignment constraints.
