checks are not needed.  If we fail to store the float as a 64-bit
integer, we just go to the runtime system.  The only extra case in
which we enter the runtime system is for NaN which should not matter.

converting the operands to 32-bit ints directly in the 
machine code stub instead of just checking if the heap 
numbers really just represent 32-bit ints and going
through the runtime system in that case.

I find this clearer and it also enables the DYNAMIC_LOCAL optimization
for code executed by eval that itself uses eval:

 eval("(function() { var x = 2; eval('1'); do stuff with x...; })()")

Add the ability to have the host embedding V8 receive a callback in the V8 thread while V8 is processing a debug callback. When V8 is processing a debug callback the thread where V8 is executing is sitting in a tight loop processing debug commands until the continue command has been executed. In some embedding situations it is beneficial to be able to call back into the embedding host from the thread where V8 is sitting. The might have functions which needs to be called to complement the JavaScript debugging.

Using the uint16_t array to pass a void* is a temporary hack.

introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.

First step in refactoring the logging system to allow the logging messages to have other destinations than an open file.

This change introduces a log message builder which builds the log message in a static string buffer instead of formatting the log message through fprintf. Currently this message can only be written to a file afterwards.

Changed the code related events to use the log message builder.
