Changes in release_ssa dump

These are changes made by tree-ssa-pre devirtualization (that triggers the
regression alone).  There are no changes in early inlining, just some indirect
calls are replaced by direct.  This should be always good idea - it seems that
simply global inliner degenerates somehow.
