  |     [scudo] Small cleanup of memory tagging code. (#166860)
  |     
  |     Make the systemSupportsMemoryTagging() function return even on system
  |     that don't support memory tagging. This avoids the need to always check
  |     if memory tagging is supported before calling th function.
  | ... 5 lines of the commit log omitted.
