Dubious primitive instantiation for GHC.Num.Integer.integerToInt# when using xpmCdcHandshake

[jvnknvlgl]

When I use xpmCdcHandshake (or specifically: xpmCdcMaybeLossy from Bittide) in my project, I get the following warning:

[WARNING] Dubious primitive instantiation for GHC.Num.Integer.integerToInt#: GHC.Num.Integer.integerToInt#: Integers are dynamically sized in simulation, but fixed-length after synthesis. Use carefully. (disable with -fclash-no-prim-warn)

I have tried to move some of the @Integers in the instantiation of the IP blocks for xpm_cdc_handshake and xpm_cdc_single to Bit or Index, but this did not resolve this warning and I can't really see where else this could go wrong.

Alright, I just discovered this is a duplicate of #2386. Using xpmCdcMaybeLossy required me to derive BitPack for one of my data types and that's what caused the warning.
