(qua last week's TC39) Specifically: - Install Symbol constructor function on the global object. - Adjust code generation for typeof. - Remove IsSymbol built-in, IS_SYMBOL macro now defined using typeof. - Remove hack that allowed symbols as constructor results, and some other special cases. - Remove symbol_delegate and GetDelegate function. - Extend ToBoolean stub to handle symbols. - Extend ToNumber to return NaN on symbols. - Poison symbol's toString function, and thereby ToString on symbols.

First of all, it has nothing to do with Isolates, it is related to the assembler at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up some platform-specific stuff on the way. Note that there are some things which still need some cleanup, like e.g. using EnumSet instead of uint64_t, making Probe() more uniform across platforms etc., but the CL is already big enough.

- Add --harmony-symbols flag. - Add Symbol constructor; allow symbols as (unreplaced) return value from constructors. - Introduce %CreateSymbol and %_IsSymbol natives and respective instructions. - Extend 'typeof' code generation to handle symbols. - Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols. - Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method. - Extend Object.prototype.toString to recognise symbols. Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).

in preparation of the introduction of ES6 'symbols' (aka private/unique names). The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders. The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

While doing this, it became clear that quite a few functions should not be static and should better live in various classes as instance methods, but I'll leave this for a later CL.

Unified parameter order of CreateHandle with the rest of v8 on the way.

With parallel recompilation enabled, objects made accessible by handles may have changed between graph construction and graph optimization. Therefore we must not assume that information on those objects remain the same between those two phases. To police this, we forbid handle dereferencing during graph optimization. Exceptions to this rule are: - Dereferencing the handle to obtain the raw location of the object. This is safe since parallel recompilation acquires RelocationLock - Some places that dereference the handle for a type check. These are checked to be safe on a case-by-case basis.

HCheckPrototypeMaps currently records the prototype and the holder of the prototype chain (both ends of the chain) and assumes that the chain elements and their maps did not change in during the entirety of Crankshaft. The actual traversal of the prototype chain happens in Lithium at code generation. With parallel compilation, this assumption is not longer correct.
