Cleaned up code layout, spacing, etc. for readability purposes and to be more
consistent with the style of LLVM's code base (and itself! it's inconsistent in some places.) No functional changes were made. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6265 91177308-0d34-0410-b5e6-96231b3b80d8
