This includes adding a new inline IsSpecObject method to the code generator. The old approach was somehow ineffecient since we would call both IsObject, IsUndetectable and IsFunction to determine if something was an object according to the spec. This change introduces a new macro that determines if something is an object according to the spec (and this does not include null). This change also corrects a few places where undetectable objects was not allowed even when they should be (priorly they would use only IS_SPEC_OBJECT_OR_NULL, which would return false on an undetectable object, the new IS_SPEC_OBJECT returns true on an undetectable object.

Fix compilation errors on X64. Error from r5080 is constructor Operand(register) with too few arguments, while constructing a dummy return value in unreachable code to avoid compiler errors. Also added explicit cast from intptr_t to int in profile-generator.cc to avoid compiler warnings, introduced in r5078.

I tried adding CheckNonEqualsHelper for int64_t, but this causes another avalanche of function resolving ambuguities. So, I ended up fooling linter.

To trace objects between snapshots, an external map of object tags is maintained. After the first heap snapshot has been taken, the map is updated by reporting object moves from the GC. If no snapshots were taken, there is no overhead (except for flag checking). I considered graph comparison algorithms that doesn't require using object tags, but they are all of a high computational complexity, and will still fail to detect object moves properly, even for trivial cases, so using tags looks like unavoidable.

Since out internal representation of a property descriptor does not have configurable and writable attributes Object.isFrozen returns true whenever an object is not extensible. This change makes use of the right method calls on our internal representation (isWritable() and isConfigurable()). Tests added directly to the mjsunit test.

The static ScopeInfo members moved into this class. The new class is named ScopeInfoObject which I am not proud of, better ideas are very welcome. Also got rid of the sentinels in the serialized scope info which saves 3 words per function and is not slower.
