64-bit instructions are split into two 32-bit words, the prefix and the
suffix. The prefix always comes before the suffix in PC order.

SVP64 is designed so that when the prefix is all zeros, no effect or
influence occurs (no augmentation) such that all standard OpenPOWER
-v3.0/1B instructions are "unaltered". This is termed `scalar identity behaviour` (based on the mathematical definition for "identity", as in, "identity matrix")
+v3.0/1B instructions are "unaltered". This is termed `scalar identity behaviour` (based on the mathematical definition for "identity", as in, "identity matrix" or better "identity transformation")
