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.

Fix by handling the case of a declaration shadowing both

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.
