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.

70dcba4024 Exclude the bit-field bits from string hash codes. String hash codes 
are always odd if the bit-field bits are included.

Modified a couple of debugger tests that relied on the ordering of
elements in descriptor arrays.  Descriptor arrays are sorted by
hash-code values, so the order changes if we change the hash code.

d2a8454d2f This change removes the %AddProperty native JavaScript function from V8. 
All uses of %AddProperty are replaced by %SetProperty.  A few uses of
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.
