  Changed paths:
    M clang/lib/CodeGen/CGExprAgg.cpp
    M clang/lib/CodeGen/CGExprScalar.cpp
    M clang/lib/CodeGen/ConstantEmitter.h
    A clang/test/CodeGen/label-array-aggregate-init.c

  Log Message:
  -----------
  [CodeGen] Fix clang crash on aggregate initialization of array of labels

Summary: Fix PR43700

The ConstantEmitter in AggExprEmitter::EmitArrayInit was initialized
with the CodeGenFunction set to null, which caused the crash.
Also simplify another call, and make the CGF member a const pointer
since it is public but only assigned in the constructor.
