Mark qt_from_latin1() as nothrow
It's used from a different TU, too, so we can't rely on the
compiler to inspect it to draw this conclusion itself.
This function has technically not a wide contract, because
the output buffer needs to be large enough to hold the result.
However, this precondition cannot be checked from within the
function, therefore no assertion can ever be added and the
nothrow marker becomes acceptable (even desireable).
