0c7af39737 Speed up access to global variables from eval scopes. Traverse the 
surrounding context to figure out if the variable could be global.  If
the variable could be global we check context extension objects at
runtime and use a global LoadIC if no variables have been introduced
by eval.

Fix crash bug when loading function arguments from inside eval.  The 
shadowed variable in the DYNAMIC_LOCAL case does not rewrite to a slot in 
that case.

b6a1cd6787 Simplify non-smi bit operation optimization. The explicit range 
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.

44b83d3e77 Add host callback for debug break. 
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.

a09832ab76 Optimize loads from variables that might be shadowed by variables 
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.

a23fd3284a Added the simplest call stack sampling and call profile in tick processor output. 
Currently only two stack frames are sampled (current function and its caller).

Output of tick processor looks like this:

 [Call profile]:
   total  call path
   15.2%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: montReduce crypto.js:583
    6.5%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: bnpSquareTo crypto.js:431
    2.9%  Builtin: KeyedStoreIC_Generic  <-  LazyCompile: montReduce crypto.js:583
    2.3%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: bnpMultiplyTo crypto.js:415

Tested under Windows, Linux and OS X.
