Subject: Move getAccessedFieldNo out of lib/AST/Expr.cpp into
 lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to use its own
 enum for visibility types instead of using
 llvm::GlobalValue::VisibilityTypes. These changes eliminate dependencies in
 the AST library on LLVM's VMCore library.
