  This commit allows us to force the relocation of functions being
  instrumented in the dyninst test suite with the -relocate flag. I added a
  forceRelocation_NP variable to the BPatch class and it is accessed and set
  by the functions hasForcedRelocation_NP() and setForcedRelocation_NP(bool).
  The method pd_Function method findInstPoints() checks if the
  forceRelocation_NP variable has been set to true and if it has, then it
  sets its relocatable_ which leads to the function's being relocated when
  it is instrumented.
