Start adding vlog95 (1364-1995) back end. This is the initial commit in an effort to build a 1364-1995 back end for Icarus Verilog. It is expected that this back end will allow the user to write 1364-2005 RTL and then using this back end (converter) generate functionally equivalent 1364-1995 compatible code. This can be used to support older tools in a work flow. The primary focus will be simulation equivalence, though I expect to verify logical equivalence as well.

vlog95: block generating a concat-Z LPM device in the compiler. Since the vlog95 code generator needs the strength information we do not want to hide it behind a concat-Z optimization. For now we abort the optimization, but in the future we could add parts of this back in (e.g. all the drivers have matching strength then replace with a normal concat and a buf-Z if the strength are not both strong. The original buf-Z should be removed to reduce the number of LPM devices).
