Clifford Wolf 6995914f3f Use ID() macro in all of passes/opt/
This was obtained by running the following SED command in passes/opt/
and then using "meld foo.cc foo.cc.orig" to manually fix all resulting
compiler errors.

sed -i.orig -r 's/"\\\\([a-zA-Z0-9_]+)"/ID(\1)/g; s/"(\$[a-zA-Z0-9_]+)"/ID(\1)/g;' *.cc

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)
