Fix default run_card for GPU

[oliviermattelaer]

With Stefan we noticed that
"output madevent_gpu" was producing a run_card with the default value set for SIMD mode...
This patch is fixing that.

Can i merge this?

IIUC this will fix the problem that Jin has reported?

Hi @oliviermattelaer sorry I will also look at this one in the afternoon. It changes the generated vector.inc, not a problem but I need to update a few scripts/tests.

Hi @oliviermattelaer can you please merge #813 first? You changed the gpucpp in that PR, I will analyse this one after that merge. Thanks

Ok, I have therefore done a rebase of the master within this branch to avoid to have to do a merge (since I do not expect everyone to branch from this branch

Hi @oliviermattelaer very good, thanks.

After including the changes from #813, I now see NO changes in generated code, so this is good to go for me (I am not at this stage testing the full workflow as you do... well I should, but I rely on you for that). So this is good to go for me.

To keep it simple, I will not include the new codegen logs, it would not add anything.

Just one comment/question, I see that in the heft codegen log this warning is now disappearing

< WARNING: coupling GC_13=-(complex(0,1)*GH) has direct dependence in aS but has QCD order set to 0. Automatic computation of scale uncertainty can be wrong for such model. 
< WARNING: coupling GC_16=(complex(0,1)*Gphi)/8. has direct dependence in aS but has QCD order set to 0. Automatic computation of scale uncertainty can be wrong for such model. 

Has the warning disappeared because the actual issue has been fixed? Or should this still give a warning?

Anyway, good to go for me.

I see that @roiser had already reacted with a thumbs-up to the review request, so I assume that he also approves this.

I will merge this directly, I think this makes it easier to progress on other fronts. Thanks @oliviermattelaer
