  Changed paths:
    M clang/lib/CodeGen/CGExprAgg.cpp
    M clang/test/CodeGenCXX/cxx11-initializer-aggregate.cpp

  Log Message:
  -----------
  Make the check for whether we should memset(0) an aggregate
initialization a little smarter.

Look through casts that preserve zero-ness when determining if an
initializer is zero, so that we can handle cases like an {0} initializer
whose corresponding field is a type other than 'int'.
