Subject: [PATCH] Remove unused dedup_map and associated includes from
 benchmarks

Summary: The dedup_map variable was declared but never used in the EmbeddingSpMDM benchmark files. This cleanup removes the dead code and the now-unused <map> and <set> includes that were only needed for that variable.
