Desirable savings in general binary size are achieved.
3. word halfword byte nibble 2-bit 1-bit reversal at multiple levels are all achieved
with grevlut. Some of these instructions were explicitly added in Power ISA v3.1
but grevlut is akin to xxeval.
-4. grevlut is expensive in hardware (estimated 20,000 gates)
+4. grevlut can be expensive in hardware (estimated 20,000 gates) but
+ like xxeval provides 512 equivalent instructions.
