mtcrf instruction used.
(model_mon_info): Return structures counting the # of CRs that the
mtcrf instruction used.
(branches, sync instructions): Do not call model functions if
WITH_MODEL_ISSUE is 0.
* mon.c (stdlib.h): Include if the system supplies one.
(mon_sort_instruction_names): New function to sort instruction
names alphabetically.
(mon_print_info): Call qsort with mon_sort_instruction_names to
sort instruction names.
sort instruction names. Don't abort if WITH_MODEL_ISSUE is 0.
* debug.h (ITRACE): Make printf_filtered arguments type correct.
* idecode_expression.h (CR0_COMPARE): Ditto.
