1d57c13b8c Fix arm and x64 build. 
The ApiGetterEntryStub is not implemented on arm or x64, but the
platform-specific implementations need to change to match the change
to the platform-independent signatures.

0672938b88 Fix a crash caused by garbage collection during generation of a 
callback load (or keyed load) IC.

The problem was that the IC code calls a stub, which can allocate and
thus trigger a GC if the stub is not already generated.  Problem is
solved by adding the ability to "try" to call a stub, trying to
generate the stub code if necessary but signaling an allocation
failure if generating the code is not possible.

41eb2f22d0 External string table. 
Instead of weak handles external strings use a separate table.  This
table uses 5 times less memory than weak handles.  Moreover, since we
don't have to follow the weak handle callback protocol we can collect
the strings faster and even on scavenge collections.

4dee8d81bd Create literal boilerplate as part of cloning in the top-level compiler. 
When generating code for object and array literals we performed
the check if the a boilerplate already exists in generated code.

In the top-level compiler we now do this check in a new runtime
function. This makes the generated code more compact for top-level code.

0bf2822266 The toplevel code generator assumed that declarations did not shadow 
parameters.  This could case the initial value to be lost or worse, a
crash.

Fix by handling the case of a declaration shadowing both
stack-allocated parameters and those in the arguments object.

This is related to V8 issue 540.

7a3a043eb2 Refactor code for generating assignments in the fast compiler. 
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.

53fbd5932a Perform string add in generated code on IA-32 platforms 
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.

fc713930ed Remove the last context dependent reference from the Script object 
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.

c76856c292 Introduce flag for using the fast compiler where possible. 
We use the fast compiler only for top-level code right now.
When always_fast_compiler is set to true, we compile with
the fast compiler whereever possible.

By default this flag is set to false.

402e356e82 Clear the compilation cache just before starting to do mark-sweep 
garbage collections when receiving idle notifications. This allows
us to get rid of source code strings and generated code in the
heap that would otherwise be kept around in idle V8 instances.

6d163d9fd0 Remove usage of JSArray in Script object 
Storing a JSArray in the Script object could cause an indirect reference from the compilation cache to a global object to be created. Now the line ends are only stored as a FixedArrya and when that is needed in JavaScript a JSArray copy is created. Changed some of the JavaScript code to cache the line ends in a local variable for better performance.
