Spelling util (#9070)
Summary:
This is a subset of https://github.com/facebook/hhvm/issues/9005, it should be easier to review/test/clear
Note: while the top level item is `hphp/util`, if a commit overlaps other directories, I'm dropping the commit. By excluding spanning commits, I reduce the risk of missing a related change (these tend to result in build/test failures which are painful) at the slight increase in additional commits for my general series.
