Unit is too big to compile #1200
Description
After upgrading to version 1.16.0 from 1.15.2, one of the files in my test suite was not able to elaborate anymore, with the error message unit <name> too big to compile. This is a netlist that is provided from Xilinx as a simulation model for one of their IPs.
I managed to generate a file, large_entity.vhd, that shows the same behavior. When the number of instances reaches ~11000, it fails in version 1.16.0. However, in version 1.15.2 it elaborated correctly up to ~33000 instances.
I have attached large_entity.vhd and a python script that generates this file.
