postreload-gcse.c (gcse_after_reload_main): Add calls to statistics_counter_event.

Browse Source 
* postreload-gcse.c (gcse_after_reload_main): Add calls to
	statistics_counter_event.
	* tree-ssa-copyrename.c (stats): Define.
	(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.
