Attempt to dedup ILMs after both syn_map and syn_generic

[jerryz123]

Previously, #812 only dedups after syn_generic, but I found that sometimes, syn_map will also unnessarily uniquify ILMs. This adds the dedup_ilm step after both syn_generic and syn_map.

I don't see a need to create new steps for these... just tack a common method (dedup_ilms) inside (at the end) of each of the two existing steps?
