93477c22d3 StringToInt rewritten. This version doesn't allocate memory for long decimals and uses percise rounding if radix 10 or a power of 2 (in other cases rounding error still may occur). Handling special values moved from Runtime_StringParseInt into StringToInt in order to make it consistent with StringToDouble.

3672624b45 Fix pop push optimization to work with partial snapshots (correct 
registration of external references in Proxy objects).
I moved the declaration of the two functions to stub-cache.h
because with all the types they use it's hard to declare them
anywhere else.  But the actual definition is still in runtime.cc
near to the place where they are used.

b148282b56 String search performance improvements: 
* Using memchr for first/only char lookup is faster than hand-coded
   loop. It processes one machine word per iteration so it helps even
   more on x64.

 * Tweaked badness computation in simple search. We pay only for the
   first char memchr scans, not for all of them.

df4471c8f3 Fix stack tweaking in array allocation 
When Array(0) or new Array(0) is handled by the generated code it is handled
by the same code as Array() and new Array(). For this to work the stack is
tweaked to remove the argument of value 0. However the argc was still passed
as 1 if a call to the runtime system was made.

When the stack is tweaked argc is also changed to 0.
