This has some follow-up changes.

Don't repeat typename in emplace_back.

This should clarify the ambiguous meaning of this function used in parallel and
non-parallel environments.

This should clarify the ownership of the vectors
passed to the ctors.

In c++11 the typename is allowed but not required in non-template contexts (http://stackoverflow.com/questions/19225458/error-c2899-typename-cannot-be-used-outside-a-template-declaration).

This is not supported by currently used visual studio compiler.

Avoid pointer access.

This also changes the locas assembler builder.
The test is updated.
