Anton Blanchard 8996fe03dc Increase OBJHASHSIZE 
I have a design that is taking quite a long time for netgen to complete LVS
checking. Profiles show a large chunk of runtime is in the hash functions.

Some of the hashtables are very sparsely populated, but others are
heavily used. One hashtable has chains of over 250. Longer term it would
be worth investigating resizing the hashtables (or perhaps using other
data strutures), but for now I looked at what changing the number of
hash buckets (OBJHASHSIZE) does for performance:

OBJHASHSIZE	time (mm:ss)
997		24:18
10093		 4:42
42073		 3:12
104729		 2:51

I somewhat arbitrarily chose 42073 which gives us a 7.6x improvement in
runtime.
