Subject: Add unit test for isLayoutIdentical(empty, empty).
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7b18ff7dd264df9675ff607d70315a8dbb370522;p=oota-llvm.git

Add unit test for isLayoutIdentical(empty, empty).
It was previously asserting in Visual C++ debug mode on a null
iterator passed to std::equal.

Test by Hans Wennborg!
