* configure{,.in} (--enable-sim-icache): If argument is define,
add -R to flags passed to igen.
* igen.c (stdlib.h): Include if the system supplies one.
(semantics_use_cache_struct): New global for -R flag to say
semantics is to use the cache structure directly rather than
putting the values into local variables.
(first_undef, last_undef): New structures to remember names to
#undef if -R.
(lf_print_c_extraction): If -R and this is semantics, emit names
as #defines pointing to the cache structure, rather than loading
the values into local variables.
(lf_print_c_semantic_function): If -R, #undef all of the names
defined in lf_print_c_extraction.
(main): Recognize -R.
* idecode_fields.h (SPR_*): Redefine spr_* macros as SPR_* to
avoid a name confict if -R passed to igen.
* ppc-instructions (mfspr, mtspr): Rename spr field to SPR.
(model_data): Add field to count the various # of CRs that the
mtcrf instruction used.
(model_mon_info): Return structures counting the # of CRs that the
mtcrf instruction used.
* mon.c (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.
* debug.h (ITRACE): Make printf_filtered arguments type correct.
* idecode_expression.h (CR0_COMPARE): Ditto.
* psim.c (psim_read_register): Ditto.
