Why did we need this? (what does this change enable us to do)

Currently VPR doesn't have a model for the SRL16 primitive.

What did it change?

Removed the SRL16 primitive.

Should it be merged upstream - if not, when can we delete it?

Can be deleted when VPR supports the SRL16 primitive.

Does VPR support SRL32CE?

Yes! And we are adding SRL16 shortly: f4pga/f4pga-arch-defs#961
