simplify-rtx.c: New file.

        * simplify-rtx.c: New file.
        * Makefile.in (OBJS): Add simplify-rtx.o
        (simplify-rtx.o): Add dependencies.
        * rtl.h (simplify_gen_binary, simplify_rtx): Add prototypes.
        * cse.c: Use simplify_gen_binary intead of cse_gen_binary.
        (cse_gen_binary, simplify_unary_operation): Delete.
        (simplify_binary_operation, simplify_plus_minus): Likewise.
        (check_fold_consts, simplify_relation_operation): Likewise.
        (simplify_ternary_operation): Likewise.
        (delete_trivially_dead_insns): Simplify the contents of the
        REG_EQUAL note before trying to substitute it into the source
        of the reg-reg copy at the end of a libcall sequence.
