/*
// Tagged pointer support
// Low-bit set means tagged object, next 3 bits (currently)
// define the tagged object class, next 4 bits are for type
// information for the specific tagged object class.  Thus,
// the low byte is for type info, and the rest of a pointer
// (32 or 64-bit) is for payload, whatever the tagged class.
