-*Architectural note: Treating the SVP64 Prefix as an "Independent" 64-bit Encoding Space and attempting
-to allocate non-Orthogonal Opcodes within it will result
-in catastrophic unviability of Simple-V. The Orthogonality of the Scalar vs Prefixed-Scalar
-spaces has to be considered inviolate, to the extent that even RESERVED spaces must be
-kept identical. The complexity at the Decode Phase by violating the RISC paradigm inherent
-in Simple-V will be unimplementable*
