Goodbye REG_FREQ_CALLS_CROSSED and REG_N_THROWING_CALLS_CROSSED
* regs.h (struct reg_info_t): Delete freq_calls_crossed and
throw_calls_crossed.
(REG_FREQ_CALLS_CROSSED): Delete.
(REG_N_THROWING_CALLS_CROSSED): Delete.
* regstat.c (regstat_bb_compute_ri): Don't calculate
REG_FREQ_CALLS_CROSSED and REG_N_THROWING_CALLS_CROSSED.
(dump_reg_info): Don't print call cross frequency.
* ira.c (combine_and_move_insns): Don't set REG_FREQ_CALLS_CROSSED
and REG_N_THROWING_CALLS_CROSSED.
