The following runtime functions (and their intrinsic counter parts) are completely unused/obsolete by now - %ToInteger - %GeneratorGetInputOrDebugPos and in addition the intrinsics for %_ToNumber and %_IsJSProxy are also dead (according to code coverage and manual verification), so drop them as well (their runtime function counterparts are still somewhat used).

This always creates the bytecode handlers as part of the builtins table regardless of the V8_EMBEDDED_BYTECODE_HANDLERS definition. Lazy deserialization of bytecode handlers is enabled for this flow by moving the three lazy bytecode deserializers from the strong roots into the builtins table (ensuring that they not marked lazy themselves). To simplify lazy deserialization, the illegal bytecode handler is made non-lazy so that GetAndMaybeDeserializeBytecodeHandler doesn't to know about it. Since the bytecode handlers are now always part of the builtins table, many bytecode specific methods are removed, including logging and in BuiltinsSerializer and BuiltinsDeserializer. Removes setup-interpreter.h, setup-interpreter-internal.cc and builtin-snapshot-utils.*.

Teach TurboFan about representation changes from Float64 to Word64 where the input value is already known to be within the Int64 or Uint64 range. While not all of these values have representations in Float64, those that do can be converted to Word64 without loss of precision. Same is true for Tagged to Word64 conversions, although here we don't (currently) need the case for Uint64 ranges, so we can skip adding an operator for that until it becomes necessary (there's a hard check in the code so it'll not silently cause trouble).

This change introduces the necessary conversion operators to convert from Word64 to other representations (Tagged, Word32, Float64, etc.), and plugs in the Word64 representation for NumberAdd/NumberSubtract, such that TurboFan will go to Int64Add/Sub on 64-bit architectures when the inputs and the output of the operation is in safe integer range. This includes the necessary changes to the Deoptimizer to be able to rematerialize Int64 values as Smi/HeapNumber when going back to Ignition later. This change might affect performance, although measurements indicate that there should be no noticable performance impact. The goal is to have TurboFan support Word64 representation to a degree that changing the TypedArray length to an uint64_t (for 64-bit archs) becomes viable and doesn't have any negative performance implications. Independent of that we might get performance improvements in other areas such as for crypto code later.
