ROCm GPU Fix

Inital hack to get us working on ROCm 7.

Not very happy about the casts and explicit calls to addCuQcomp and mulCuQcomp

[TysonRayJones]

Are you sure addCuQcomp is necessary? The ROCm 6.0 changelog mentions only * and / issues, and your diff doesn't change every + operator into a addCuQcomp call (consider this one). So I suspect

amp = addCuQcomp(amp, mulCuQcomp(coeffs[q], inAmps[q][n]));

could instead be just

amp = amp + mulCuQcomp(coeffs[q], inAmps[q][n]);

and addCuQcomp() deleted.

I'm not even sure that's better, but it'd help the investigation by shrinking the diff
