Rename |property_attributes| to |initial_property_attributes| and ensure that it is used as a storage of values only for AccessorInfos installed in API Templates (i.e. ObjectTemplate and FunctionTemplate). When an AccessorInfo is installed directly into an existing JS object (via JSObject::SetAccessor) or into a DescriptorArray (when certain V8 objects' shapes are configured) it is not necessary to thread attributes being set through the AccessorInfo instance.

This is the first step towards lazy-deserializing bytecode handlers. Bytecode handler code objects are now serialized into the builtins snapshot area (which, like many other related concepts, has become somewhat of a misnomer now that it contains both builtins and handlers). Handlers are still eagerly-deserialized upon Isolate creation. This will change in follow-up CLs.

This attaches a constructor to the bound function map so we can identify the creation context using the map, it chooses the bound-function map from the same realm as the target's creation context (additionally to avoid memory leaks and unnecessary transitions), and finally drops the loop unwrapping bound functions in GetCreationContext.

The current implementation overapproximates the possible_nondeterminism_ bit by setting it whenever a NaN value is reinterpreted as integer, or stored to memory. This hides bugs in the interpreter that are handled as possible nondeterminism even though they are not. This CL fixes this by only setting the bit if a binary floating point operation is executed and one of the inputs is a NaN.

The current_cpu value was erroneously removed from the build config json. In multi-arch builds, each toolchain subdirectory in the build-product output emits its own build-config json, where current_cpu determines the architecture type of the sub-build. Correctness-fuzzer runs could wrongly determined x86 sub-builds as x64.

The motivation for this is that it greatly reduces the RelocInfo size. This also results in a small improvement in compile time. Note: This CL was based on https://codereview.chromium.org/2651833003, and basically reverts that CL (but handles code changes and some minor bugs in previous code).

Abstract equality comparison of a BigInt and a String converts the latter to BigInt. This conversion can fail; since we do not want to pass a context to the comparison function, we must signal such failure without throwing an exception. This CL uses the existing ShouldThrow enum to configure behavior of String-to-BigInt conversion, moving it out of Object into globals.h.
