Add a class that is useful for hacking around linking problem due to
pass implementations not being linked in when they are used if the
implementation is in a .a file.
- Fighting with linking problem due to removing the ::ID elements. Now the
implementation .cpp files for analyses are not being included into gccas
and friends because it is linking to the .a file and there is no explicit
symbol reference to bring in the .o file. The new IncludeFile hack is the
result.
