Subject: [PATCH] libstdc++/77645 fix deque and vector xmethods for Python 3
Authentication-results: sourceware.org; auth=none

The problem for these xmethods is that in Python 3 division of two
integers produces a float, and GDB then doesn't allow that value
to be used for pointer arithmetic (https://sourceware.org/PR20622).

	PR libstdc++/77645
	* python/libstdcxx/v6/xmethods.py (DequeWorkerBase.__init__)
	(DequeWorkerBase.index, VectorWorkerBase.get): Cast results of
	division to int to work with Python 3.

Tested x86_64-linux, committed to trunk.

I'll fix it for gcc-5 and gcc-6 too.
