Tested x86_64-linux, committed to trunk.

This should probably go on the 4.9 branch too, although we could leave
the old default cosntructor semantics and just fix the conversion
operator.

Looking at the comparison functions of basic_string_view I noticed
that these are not constexpr (nor seem to be other functions such as
find()).

I think we need full C++14 constexpr to make them so though.
Most of these involve loops and such.
