Patch description has been updated with an explanation.

The bug was that Clang wasn't calling the default-member intializer in the 
first initializer, which the CodeGen test asserts. The second initializer is 
irrelevant - it's only function is to provide the expected value of the 
initialized field. In fact, changing the test assertion to be the same as that 
in the bug report (asserting that the values of the fields in the two objects 
are equal) is worse because that test would pass if we value-initialize the 
fields instead of calling the default initialization expression for both 
objects.
