(rename_ssa_copies): Count coalesced SSA_NAMEs. Add call to statistics_counter_event. * tree-ssa-math-opts.c (reciprocal_stats, sincos_stats): Define. (bswap_stats, widen_mul_stats): Define. (insert_reciprocals): Increment rdivs_inserted. (execute_cse_reciprocals): Zeroize reciprocal_stats. Increment rfuncs_inserted. Add calls to statistics_counter_event. (execute_cse_sincos_1): Increment inserted. (execute_cse_sincos): Zeroize sincos_stats. Add call to statistics_counter_event. (execute_optimize_bswap): Zeroize bswap_stats. Increment fields of bswap_stats. Add calls to statistics_counter_event. (convert_mult_to_widen): Increment widen_mults_inserted. (convert_plusminus_to_widen): Increment maccs_inserted. (convert_mult_to_fma): Increment fmas_inserted. (execute_optimize_widening_mul): Zeroize widen_mul_stats. Add calls to statistics_counter_event.
