8cfffd3a3e Sign-extend values used to index arrays (and Simplify
SetOperandsForMemInstr significantly).  Load and Store
no longer have any indices.  Eliminate spurious sign-extension
on a cast to float/double.

f20816bc78 - 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.
