phobos commit, revision 2178


user: rsinfu

msg:
Made std.array empty(), save() and overlap() "@safe pure nothrow".

overlap: nested functions min() and max() are ad-hoc workaround to make the function pure nothrow.

front(), back(), popFront() and popBack() depend on std.utf, and they are unchanged for now.
