* combine.c: Include params.h.
(count_rtxs): New function.
(record_value_for_reg): If replace_rtx would replace at least
2 occurrences of REG in VALUE and TEM is really large, replace REG with
(clobber (const_int 0)) instead of TEM.
* params.def (PARAM_MAX_LAST_VALUE_RTL): New.
* params.h (MAX_LAST_VALUE_RTL): New.
* Makefile.in (combine.o): Depend on $(PARAMS_H).
