I didn't find any dump_rtx - instead, I used print_inline_rtx which
seems to be what we need to output to stdout, instead of stderr.
Updated version of the patch is attached. Ok for trunk?

Changelog:
2012-11-30  Michael Zolotukhin  <michael.v.zolotukhin@intel.com>

        * Makefile.in: Add target mddump, build/genmddump.o.  Extend
        genprogrtl with mddump.
        * genmddump.c: New.

Thanks, Michael
