I've done this, and also added valid_utf16be/make_from_utf16be too,
for similar reasons (it's a pretty obscure use-case, but if you have a
UTF-16BE string whose first character is zero-width-unbreakable-space,
then you can't use make_from_utf16, as that routine will assume the
first character is a BOM, and discard it, so you have to prepend the
BOM yourself).

I've also added tests which pass on all three compilers.

May I check these in?
