As time went by, a few files have become mis-formatted w.r.t. clang-format. This was made worse by the fact that formatting was not being enforced in extensionless headers. This commit simply brings all of libcxx/include in-line with clang-format again. We might have to do this from time to time as we update our clang-format version, but frankly this is really low effort now that we've formatted everything once.
