John McCall	4e8ca4fa14	Significantly simplify CGExprAgg's logic about ignored results: ... if we want to ignore a result, the Dest will be null. Otherwise, we must copy into it. This means we need to ensure a slot when loading from a volatile l-value. With all that in place, fix a bug with chained assignments into __block variables of aggregate type where we were losing insight into the actual source of the value during the second assignment. llvm-svn: 159630	2012-07-02 23:58:38 +00:00
