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.
