an internal error when compiling templateified jscre.  We really need

89ac41aff9 If an allocation is so huge that we cannot code the size needed in the failure 
object then we just return an out of memory failure object (instead of a retry
after GC failure object).  Not all places that checked for retry-after-GC were
able to handle an immediate out of memory failure.

4f7b6654d4 This change rewrites some of the code to add properties to an object. 
It removes the ReplaceConstantFunction code, and replaces it with
new ConvertDescriptorToField code, that is also used in other places.
Functions CopyRemove and CopyReplace on DescriptorArray are removed.
Function AddFastProperty is simplified by removing the 
CONSTANT_TRANSITION case.

76b1efea2d - Specialized slow-case string equality nine ways based on the 
underlying string representation of the two strings involved.
- Renamed ascii and two byte string classes to sequential ascii and
  sequential two byte, and renamed IsAscii and friends to
  IsAsciiRepresentation.  This is to make a clear distinction between
  strings with an ascii/two-byte representation, of which there is
  four, and flat sequential ascii/two-byte string.

c0e04e1e86 Fixed unsafe code where a GC could occour after a Handle had been deferenced. 
instances->set(i, *GetScriptWrapper(script));

GetScriptWrapper can call GC. The failure have only been seen on ARM, where
the g++ compiler pulls out the object from the instances handle to a register
before calling GetScriptWrapper causing set to be called on an object which
may have moved.

Marked a test on ARM as no longer flaky, whereas two other fails consistently
but that is no longer related to the problem fixed above.

are always odd if the bit-field bits are included.

Modified a couple of debugger tests that relied on the ordering of

hash-code values, so the order changes if we change the hash code.

IgnoreAttributesAndSetLocalProperty are added, and the runtime version
of it adds a PropertyAttributes argument.  Only the JSObject class
in objects.cc now uses AddProperty, and it can become private.
