Issue 10609 - Refused UFCS in __traits(compile) 

http://d.puremagic.com/issues/show_bug.cgi?id=10609

While fixing 10609, I found a relate bug 10618.
[Issue 10618](http://d.puremagic.com/issues/show_bug.cgi?id=10618) - Template instance member access disallowed in dynamic array allocation

Both fixes are necessary.
