The "Address" type is V8's general-purpose type for manipulating memory
addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
are undefined behavior except within the same array; since we generally
don't operate within a C++ array, our general-purpose type shouldn't be
a pointer type.

This changes the encoding of the {HandlerTable} from an array of Smi
values to a byte array. It allows embedding of said array into the
instruction stream of {Code} objects (similar to how safepoint tables
work). For interpreted bytecode the table is attached as a {ByteArray}
to the bytecode.

The advantage of this approach is a more compact encoding and also the
ability to move such tables easily off the GC'ed heap if needed (as is
done for WebAssembly code for example).
