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.

This adds a code stub which can do most of what Heap::AllocateConsString can do.

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.

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.

Remove the different length string types
...
The different length string types was used to encode the string length and the hash in one field. This is now split into two fields one for length and one for hash. The hash field still encodes the array index of the string if it has one. If an array index is encoded in the hash field the string length is added to the top bits of the hash field to avoid a hash value of zero.
On 32-bit this causes an additional 4 bytes to be used for all string objects. On 64-bit this will be half on average dur to pointer alignment.

Implement IS_OBJECT and IS_FUNCTION as inlined runtime functions.

Summary:
This change fixes a performance regression introduced by the special
handling of regular expressions in typeof expressions.
As a result we regain ~8% speedup on 3d-raytrace and ~13% on boyer
(vs bleeding edge)
Description:
The macros IS_OBJECT and IS_FUNCTION are frequently used in the
JS runtime functions.
By introducing new inlined runtime functions %_IsFunction and %_IsObject
we avoid invoking the more expensive %_ClassOf function plus comparing
its result to a string.

Fixed bug in pixel array inline cache on x64. The value was not
...
zero-extended as it should be. Therefore, the index into the pixel
array could influence the value on reads.

Add DebugMessageDispatchHandler
...
A callback on the debugger thread when a message is received. Allows the
embedding application to wake up the main thread in order to handle the
message. Useful when the embedding application is idle and sitting in a
select() call.

Restore invariant (next of first deallocated must point to the head) before calling into weak
...
callbacks.
Otherwise if callback allocates a new handle, it could orphan some global handles (with disastorous
consequences if those global handles are cached).
