Version 3.3.3
Added support for generating Visual Studio solution and project files using GYP.
Implemented support for ARM EABI calling convention variation where floating-point arguments are passed in registers (hardfloat).
Added Object::HasOwnProperty() to the API.
Added support for compressing startup data to reduce binary size. This includes build time support and an API for the embedder to decompress the startup data before initializing V8.
Reduced the profiling hooks overhead from >400% to 25% when using ll_prof.
Performance improvements and bug fixes on all platforms.
