New abstract class CodeEventListener was created. CodeEventLogger which is the base class for Jit, LowLevel and CodeAddressMap loggers was inherited from CodeEventListener. CodeAddressMap class was moved to serializer.cc because serializer is the only user for it. Actually it collects code names and pushes them to the standard log as SnapshotCodeNameEvent. So I extracted this code into separate function CodeNameEvent. It happens that this method works only when Serializer serializes an object. So I added direct log call there. CodeEventLogger class declaration was moved to the header because CodeAddressMap needs it. The code for the nested class CodeEventLogger::NameBuffer was left in the cc file. CpuProfiler now is inherit CodeEventListener but not used the loggers infrastructure yet due to the complex initialization schema. I'd like to fix that in a separate cl.

The gc should be able to traverse all AllocationSites for decision making. The sites are threaded into a weak list. Special problems include: * Allocations of AllocationSites occur in generated code, so generated code needs to be able to add to the list. For now I have a special hydrogen instruction, though it would be nice to use general purpose instructions. * The snapshot contains AllocationSites, and these need to be re-threaded into the list on deserialization. Something nice is that the AllocationSites are only created in old space, so a special new space visitor isn't required.

in preparation of the introduction of ES6 'symbols' (aka private/unique names). The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders. The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

the speed of deserializing code. The current startup time improvement for V8 is around 6%, but code deserialization is speeded up disproportionately, and we will soon have more code in the snapshot. * Removed support for deserializing into large object space. The regular pages are 1Mbyte now and that is plenty. This is a big simplification. * Instead of reserving space for the snapshot we actually allocate it now. This removes some special casing from the memory management and simplifies deserialization since we are just bumping a pointer rather than calling the normal allocation routines during deserialization. * Record in the snapshot how much we need to boot up and allocate it instead of just assuming that allocations in a new VM will always be linear. * In the snapshot we always address an object as a negative offset from the current allocation point. We used to sometimes address from the start of the deserialized data, but this is less useful now that we have good support for roots and repetitions in the deserialization data. * Code objects were previously deserialized (like other objects) by alternating raw data (deserialized with memcpy) and pointers (to external references, other objects, etc.). Now we deserialize code objects with a single memcpy, followed by a series of skips and pointers that partially overwrite the code we memcopied out of the snapshot. The skips are sometimes merged into the following instruction in the deserialization data to reduce dispatch time. * Integers in the snapshot were stored in a variable length format that gives a compact representation for small positive integers. This is still the case, but the new encoding can be decoded without branches or conditional instructions, which is faster on a modern CPU.

The deoptimizer generates full-code-generator code and relies on it having the same layout as last time. This means that the code the full code generator makes for the snapshot should be the same as the code it makes later. This change makes the full code generator create more consistent code between mksnapshot time and run time. This is a bug fix and a step towards making the snapshot code more robust.

with more JS code that is loaded into the VM before writing the snapshot. Get rid of the hard coded limit on the partial snapshot cache size. This change disables most of the serializer tests for the snapshot build of the VM: It's getting too complicated to support both booting from a snapshot and then creating a new snapshot from the same VM or loading more code with another snapshot in the same VM.
