RFR(S): 8237007: Shenandoah: assert(_base == Tuple) failure during C2 compilation

Hi Roman,

Thanks for looking at this. I would have to list all variants in the
switch:

CMoveD
CMoveVD
CMoveF
CMoveVF
CMoveI
CMoveL
CMoveP
CMoveN

That doesn't seem better to me and is quite error prone too.

Roland.
