This is a port of the IA-32 version from r3400 (http://code.google.com/p/v8/source/detail?r=3400). In the X64 version the additional registers are used to avoid loading the instance type and arguments several times.

Fix by handling the case of a declaration shadowing both

1. Refactor the structure of VisitAssignment: The existing code is not ideal 
to be extended with support for compound assignments.

2. Reuse common code for keyed property assigments: Now variables rewritten 
to a property (.arguments access) are treated like normal keyed property
assignments. This allows us to remove some code duplication.

This adds a code stub which can do most of what Heap::AllocateConsString can do. It bails out if the result cannot fit in new space or if the result is a short (flat) string and one argument is an ascii string and the other a two byte string. It also bails out if adding two one character strings as Heap::AllocateConsString has special handling of this utilizing the symbol table. The stub is used both for the binary add operation and for StringAdd calls from runtime JavaScript files. Extended the string add test to cover all sizes of flat result stings.

For scripts originating from a call to eval the Script object used to hold a reference to the function from where the eval was called together with the code offset within that function of the eval call. This is used by the stack trace and is part of the debugger protocol. In order to avoid storing the function the script, the position within the script and the name of the function calling eval is stored instead. This avoids holding context dependent objects in the script object.

The calculation of the position of the eval in the script holding the eval is now done when the eval script is compiled as it is not possible to postpone this unless a reference is kept to the generated code for the function calling eval.

The check for the number og GC's required is now 1 or 2 instead of two to get rig of failures on ARM.

Updated the test to keep the code used by the test in the compilation cache by compiling it in another context. This makes the remaining issue with the eval cache more explicit.

The constant for the return sequence length (JSReturnSequenceLength) was
defined in debug.h. Since this constant are also needed outside the debugger code
I moved them into assembler-xxx.h. Otherwise compiling with debuggersupport=off
