  Move unsafe buffers inside header guard macros
  
  While this is exactly opposite of what Chromium has chosen to do,
  there is an issue with clang-format trying to indent preprocessor
  directives four spaces relative to include guard. This is because
  Angle's .clang-format file specifies IndentPPDirectives: AfterHash
  but Chromium's does not. The current placement is sufficient to
  throw off clang-format's guard detection since the guard macro no
  longer covers the entire file.
