Apps that create new programs during the run need to have them
deleted on loop. This CL handles that. It does not handle programs
that have been deleted and need to be recreated, or that have been
modified otherwise. An assert has been included to catch that for
future needs.

With this CL, entries like this will show up in ResetReplay:

  ...
  glDeleteProgram(gShaderProgramMap[120]);
  glDeleteProgram(gShaderProgramMap[121]);
  ...
