889cbe55b8 Fix a bug in the regexp caching. Also add a few more places to 
cache.  We now cache most of the places where Opera cache and
one or two where they do not cache for some reason.  Since
these optimizations aren't necessarily useful on real code we
may remove them if and when the Dromaeo website makes the
benchmarks harder to game.

9202e05016 Fix bug in the count operation where we statically know the input is a smi. 
Even if we know that the input to a count operation is a smi we still need to check if the result overflowed (and becomes a heap number).

Also fix the smi loop analysis to take two border cases correctly into account.

800b6df2a6 Correct handling of adding a string and a smal integer 
The fast case of looking up the string convertion of the smi did not handle the case where left/reghe operands could be in eax/edx instead of edx/eax which is the default.

Also got rid of creating an internal frame for calling string and instead patched the argument on the stack and performed a tail call.

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.

Moved all the logic to a function on SharedFunctionInfo (including the flag check) to make things more readable.

Changed the check for setter to do a lookup for a named setter for each of the properties assigned in the constructor.

Added tests using accessors and interseptors set through the API.

Added fast case objects to the mjsunit test.

3c0d77f32e Fix stack corruption when calling non-function. 
Fix for issue 603.

Revision r3484 removed the property name from the call stack for
call ICs.  When a non-function was called via a call IC and
Function.prototype.call, an extra value was left on the stack that the
caller could not know to clean up.

Fix is to change the JS builtin used for calling non-functions.  It
now gets the callee as receiver, rather than iterating stack frames
and finding it on the expression stack of its JS caller.

1c2b2ac9c6 Fix construction of simple objects with setters on prototype 
Simple objects which are constructed without calling the actual constructor function did not take setters defined on prototype chain of the new object into account.

Constructing objects this way is now not done if there are setters involved on the prototype chain of the new object.

This only fixes the case where the setter is found when the first object from a constructor is created. If the prototype chain is changed new objects will on take any change to setters into account.
