Subject:         * dbgcnt.def (cfg_cleanup, cprop1, cprop2, dce_fast, dce_ud,
 dse1,         dse2, gcse, if_conversion, if_after_combine, if_after_reload,  
       jump_bypass): New counters.         * cfgcleanup.c (cleanup_cfg): Add
 dbg_cnt.         * dce.c (gate_ud_dce): Same.         (gate_fast_dce): Same. 
        * dse.c (gate_dse1): New function.         (gate_dse2): New function. 
        (gate_dse): Merge results of new gate functions.         * gcse.c
 (gcse_main): Bracket cprop1 and cprop2 with dbg_cnt.        
 (gate_handle_jump_bypass): Add dbg_cnt.         (gate_handle_gcse): Add
 dbg_cnt.         * ifcvt.c (gate_handle_if_conversion): Same.        
 (gate_handle_if_after_combine): Same.         (gate_handle_if_after_reload):
 Same.         * Makefile.in: Add DBGCNT_H to cfgcleanup.o and ifcvt.o.
