[PATCH] D34324: [clang-format] let PointerAlignment dictate spacing of function ref qualifiers

[Jacob Bandes-Storch via Phabricator via cfe-commits]

The original changes for ref qualifiers in https://reviews.llvm.org/rL272537 
and https://reviews.llvm.org/rL272548 allowed function const+ref qualifier 
spacing to diverge from the spacing used for variables. It seems more 
consistent for `T const& x;` to match `void foo() const&;`.
