Hi,
As Segher and Mike pointed out, the define_insn_and_split should avoid
to use empty split condition if the condition for define_insn isn't empty,
otherwise it can sometimes leads to unexpected consequence.
This patch is to fix some places like this.

Hello Andre,
thank you so much for your quick reply. I also noticed that but somehow with
GCC 8.1 and GDB 8.1 this example works, no GDB endless loop with showing us
backtrace.
Hi,
this patch updates costs of integer divides to match actual latencies (the
scheduler model already does the right thing). It is essentially no-op, since
we end up expanding idiv for all sensible constants, so this only may end
up disabling vectorization in some cases, but I did not find any
