This adds the gyp flag v8_enable_i18n_support (off by default), and the
v8 flag FLAG_enable_i18n (on by default, but without effect if
v8_enable_i18n_support is off).

If the top optimized code in call stack is at the point that does not support
deoptimization, then treat the maps in the code as strong pointers.

Note that other optimized code in call stack must support deoptimization
because of the call instruction with side-effects.

When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was.

This change adds builtin id to CodeEntry objects. It will be used later to add similar top frame analysis for FunctionApply and probably other builtins.

This adds an ASSERT that the entry_stack_ of the Isolate is
empty upon destruction. The default Isolate is an exception
here, as it may still contain an entry stack item upon

Each CpuProfileNode has resource_name string property.
It cost us N * strlen(resource_name) where N is number of functions in the collected profile.
We could transfer script_id instead of resource_name so it would reduce transfer

Currently synthesizes Smi as the lower bound for numeric operations (except for +, which might result in a string). That would need to change in places where we want to track constants as type feedback.

- Constants globals are inlined into Hydrogen code using code dependencies that invalidate the Crankshafted code when global PropertyCells or the global object change.
- The more general case generates code that is just as good as the hand-written assembly stubs on all platforms.
