Googletest export

Fix mocking method arguments with templated copy constructors.

A previous change removed workarounds for old compilers from googletest and googlemock. Unfortunately, a bit of code that started as a workaround for Symbian's C++ compiler is still needed to avoid copy/move constructor ambiguity when mocking functions with certain argument types.

The test case added by this CL is extracted from Chrome's codebase, and was discovered while attempting to roll googletest.
