[PATCH] [libstdc++] Add operator-> xmethod to std::unique_ptr

[Doug Evans]

Hi.

This patch adds operator-> xmethod support for std::unique_ptr.

Regression tested on amd64-linux.

Ok to commit?

2015-04-30  Doug Evans  <dje@google.com>

	* python/libstdcxx/v6/xmethods.py (UniquePtrMethodsMatcher): Add
	operator-> support.
	* testsuite/libstdc++-xmethods/unique_ptr.cc: Add tests for
	operator->.
