* combine.c (combine_simplify_rtx): Adjust call to use
simplify_relational_operation. Do not use SELECT_CC_MODE
when a comparison already has a MODE_CC mode.
(simplify_set): simplify_relational_operation may now
return another relational expression.
* cse.c (fold_rtx): simplify_relational_operation now
takes of computing the comparison mode.
* dojump.c (compare_from_rtx): Use simplify_relational_operation,
remove dead code.
(do_compare_rtx_and_jump): Likewise.
* integrate.c (subst_constants): simplify_relational_operation
may now return another relational expression.
* simplify-rtx.c (simplify_gen_relational): Move most code to
the new simplify_relational_operation and
simplify_relational_operation_1 functions.
(simplify_relational_operation): Rewritten.
(simplify_relational_operation_1): New function.
(simplify_ternary_operation): simplify_relational_operation
may now return another relational expression.
(simplify_rtx): Remove unnecessary temp variable.
