Hi
this patch updates cost of znver4 mostly based on data measued by Agner Fog.
Compared to previous generations x87 became bit slower which is probably not
big deal (and we have minimal benchmarking coverage for it). One interesting
improvement is reducation of FMA cost. I also updated costs of

There is no Immediate operand of ins "rol" according to the B-ext,
so the immediate operand should be loaded into register at first.
But we can convert it to the ins "rori" or "roriw", and then one
immediate load ins can be reduced.
So I added some conditions when reverse the
The first patch is

Accroding to Jeff's suggestion I added some conditions when reverse the rotate
shift during RTL expansion and RTL optimization.

Thanks, it's still the same reason - we isolate a nullptr case and end up with
