Paul Mackerras 24a4a796ce execute: Consolidate count-leading/trailing-zeroes implementations 
This adds combinatorial logic that does 32-bit and 64-bit count
leading and trailing zeroes in one unit, and consolidates the
four instructions under a single OP_CNTZ opcode.

This saves 84 slice LUTs on the Arty A7-100.
