This commit does a pass of clang-format over files in libc++ that don't require major changes to conform to our style guide, or for which we're not overly concerned about conflicting with in-flight patches or hindering the git blame. This roughly covers: - benchmarks - range algorithms - concepts - type traits I did a manual verification of all the changes, and in particular I applied clang-format on/off annotations in a few places where the result was less readable after than before. This was not necessary in a lot of places, however I did find that clang-format had pretty bad taste when it comes to formatting concepts. Differential Revision: https://reviews.llvm.org/D153140
