Debug flag `--debug-generate-inits` fails if sizes of parameters are based on data #1317

Added in #1306.

Not clear what the correct thing to do is - maybe also generate data at the same time? Just omit them?

I'd say the correct thing to do is to require a data file as input. Actually, even --debug-generate-data could accept partial input data. For instance you might have data { int N; vector[N] x; } and you want to generate data with N=10.

That would be the most useful choice, but also the most complicated I believe.
