* basic-block. (profile_record): New struct, moved from passes.c.
* cfghooks.h (struct cfg_hooks) <account_profile_record>: New hook.
(account_profile_record): New prototype.
* cfghooks.c (account_profile_record): New function.
* tree-cfg.c (gimple_account_profile_record): New function
(gimple_cfg_hooks): Add it.
* cfgrtl.c (rtl_account_profile_record): New function
(rtl_cfg_hooks, cfg_layout_rtl_cfg_hooks): Add it.
* passes.c (check_profile_consistency): Simplify. Move IR-dependent
code around using cfghooks machinery.
