what do you need gimple-pretty-print.h and rtl.h for?

the gimple stuff really belongs in to gimple-pretty-print.c

perfect candidate for dumpfile.c

You can do this re-shuffling as followup, but please try to not include rtl.h
or gimple-pretty-print.h from tree-dump.c.  Thus re-shuffling required by that
do now.  tree-dump.c should only know about dumping 'tree'.

I am sure you need a gazillion more testsuite adjustments?  Thus, did you
really test the patch by a bootstrap and a toplevel make -k check for
regressions?

it looks like changes to these files are only renaming of existing
