In preparation for introducing writing capabilities for each of these classes, I would like to adopt a Foo / FooRef naming convention, where Foo indicates that the class can manipulate and serialize Foos, and FooRef indicates that it is an immutable view of an existing Foo. In other words, Foo is a writer and FooRef is a reader. This patch names some existing readers to conform to the FooRef convention, while offering no functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@301810 91177308-0d34-0410-b5e6-96231b3b80d8
