fca7b2cefa Refactor the scanner interface 
No need to create sub strings for lazy compiles. The scanner will start from the start position provided.

Moved the creating of character streams into the scanner where possible. This uses a input buffer in the scanner class instead of a stack allocated one.

Added a UTF16 buffer for reading external ascii strings (by templating the external two byte string one) as all the source for the builtins are exposed as external ascii strings.

9f681fa9d6 Small API improvements: 
* Added Get and Set taking uint32_t for faster and more convenient
   access to elements.

 * Added less verbose casting for handles. Now instead of
       v8::Local<v8::String>::Cast(args[0])
   one can write
       args[0].As<v8::String>().

16b34b8c6e Parametrize C++ splay tree with allocator. 
Thus, now there is a "generic" SplayTree and its Zone-bound
specialization ZoneSplayTree.

This is needed for my reimplementation of profiler tree generation in
C++. As generation is performed in a separate thread, Zone can't be
used, because it intentionally not thread-safe.

b7f0608c9a Logging-related changes. 
- when logging 'open-tag' / 'close-tag' events, don't depend on
   FLAG_log (as it may be not enabled, e.g. in Chromium);

 - PauseProfiler / ResumeProfiler were supposing that they
   use 'is_logging_' var exclusively, thus preventing any
   other logging that may be turned on for diagnostic purposes.

8398287070 Refactor the code cache to handle large number of properties on the global object. 
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.

The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.
