[PATCH 1/3] Add power10 zero cycle moves for switches & indirect jumps

Add power10 zero cycle moves for switches. Power10 will fuse adjacenet 'mtctr' and 'bctr' instructions to form zero cycle moves. This code exploits this fusion opportunity. I have built bootstrapped compilers with this patch on little endian power9 and power10 systems with no regressions. Can
