Subject: [PATCH, SMS] Avoid considering debug_insn when calculating SCCs

Hello,

The attached patch avoids considering debug_insn when calculating SCCs.
With this change the existence of debug_insn does not influence
the scheduling order and rec_MII.

Bootstrap and regtest on ppc64-redhat-linux and regtest on arm-linux-gnueabi.

OK for mainline?

Thanks,
Revital

Changelog:

* ddg.c (find_nodes_on_paths): Ignore DEBUG_INSNs.
