// from the pointer in one efficient operation (bitwise AND). The number of
// available bits is limited in the following way: on x64, bits [47, 64) are
// generally available for tagging (userspace has 47 address bits available).
// On Arm64, userspace typically has a 40 or 48 bit address space. However, due
// to top-byte ignore (TBI) and memory tagging (MTE), the top byte is unusable
// for type checks as type-check failures would go unnoticed or collide with
// MTE bits. Some bits of the top byte can, however, still be used for the GC
// marking bit. The bits available for the type tags are therefore limited to
// [48, 56), i.e. (8 choose 4) = 70 different types.
// The following options exist to increase the number of possible types:
// - Using multiple ExternalPointerTables since tags can safely be reused
// across different tables
// - Using "extended" type checks, where additional type information is stored
// either in an adjacent pointer table entry or at the pointed-to location
// - Using a different tagging scheme, for example based on XOR which would
// allow for 2**8 different tags but require a separate operation to remove
// the marking bit
//
// The external pointer sandboxing mechanism ensures that every access to an
// external pointer field will result in a valid pointer of the expected type
// even in the presence of an attacker able to corrupt memory inside the
// sandbox. However, if any data related to the external object is stored
// inside the sandbox it may still be corrupted and so must be validated before
// use or moved into the external object. Further, an attacker will always be
// able to substitute different external pointers of the same type for each
// other. Therefore, code using external pointers must be written in a
// "substitution-safe" way, i.e. it must always be possible to substitute
// external pointers of the same type without causing memory corruption outside
// of the sandbox. Generally this is achieved by referencing any group of
// related external objects through a single external pointer.
//
// Currently we use bit 62 for the marking bit which should always be unused as
// it's part of the non-canonical address range. When Arm's top-byte ignore
// (TBI) is enabled, this bit will be part of the ignored byte, and we assume
// that the Embedder is not using this byte (really only this one bit) for any
// other purpose. This bit also does not collide with the memory tagging
