Nemanja Ivanovic c196e2ca48 [PowerPC] Clear the set of symbols that need to be updated in MCTargetStreamer ...

We have added code to correct the .localentry values on assignments. However, we
never clear the set so presumably it will still contain the (now dangling)
MCSymbol pointers across a call to finish() and reset() in the streamer.

This is based on my speculation that it is the reason we are getting
segmentation faults mentioned in https://bugs.llvm.org/show_bug.cgi?id=45366
