[Hexagon] Fix insertion point for pointer difference calculation

HVC::calculatePointerDifference inserts temporary instructions for
simplification, and calulation of known bits. These instructions were
inserted at the end of a basic block (after the terminator), which
caused BB->getTerminator() to return nullptr. This, in turn, caused
a crash when a PHI instruction was examined in computeKnownBits.
