TryCompileCode(): Prevent warning on return value
Some newer compilers warn in situations where the returned local
variable could be movable, but a C++11 defect meant older compilers
may still return a copy when a type conversion is involved. Adding
the suggested std::move prevents that warning on that compiler, but
creates a new warning on others. Constructing the actual return type
explicitly with the suggested std::move on the constructor argument
keeps both sets of compilers happy.
