  Changed paths:
    M clang/lib/CodeGen/CGExprConstant.cpp
    M clang/test/CodeGenCXX/no-unique-address.cpp

  Log Message:
  -----------
  Fix miscompile with [[no_unique_address]] struct fields.

If a zero-sized field has a non-trivial initializer, it should prevent
the overall struct initialization from being folded to a constant during
IR generation. Don't just ignore zero-sized fields entirely in IR
constant emission.
