Marcelina Kościelnicka 38a0c30d65 Get rid of dffsr2dff.
This pass is a proper subset of opt_rmdff, which is called by opt, which
is called by every synth flow in the coarse part.  Thus, it never
actually does anything and can be safely removed.

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes.
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)

Piotr Esden-Tempski e3a12b57f5 Use -E sed parameter instead of -r.
BSD sed equivalent to -r parameter is -E and it is also supported in GNU
sed thus using -E results in support on both platforms.

Micah Elizabeth Scott 93f6f68b65 Remove nonportable "-r" option from xargs
On Linux, this avoids an empty "rm -f" call when there's nothing to clean. But it isn't portable, and it causes the build to fail on Mac OS. It doesn't seem to be harmful to remove this option entirely, and it's a step toward fixing the Mac build.
