Hi!

Apparently, emit_cmp_and_jump_insns can silently generate wrong code
for wider modes on some targets, so this patch changes all those calls in
internal-fn.c to do_compare_rtx_and_jump, which is a wrapper around
emit_cmp_and_jump_insns that should handle the wider mode comparison
expansion.  Unfortunately, the order of arguments is different :(.

No new testcases provided, the existing testsuite exhibited this on various
targets.

Bootstrapped/regtested on x86_64-linux and i686-linux, tested on the
testcases for ia64 and Uros tested the testcases on Alpha (in both cases
they previously failed), ok for trunk?

        * internal-fn.c (expand_arith_overflow_result_store,
        expand_addsub_overflow, expand_neg_overflow, expand_mul_overflow): Use
        do_compare_rtx_and_jump instead of emit_cmp_and_jump_insns everywhere,
        adjust arguments to those functions.  Use unsignedp = true for
        EQ, NE, GEU, LEU, LTU and GTU comparisons.
