Summary: This directory is opted-in to clang-format but is not format-clean. This blocks continuous formatting from being enabled on fbcode, and causes hassle for other codemods that leave inconsistent formatting. This diff runs clang-format, which is widely used and considered safe. If you are unhappy with the formatting of a particular block, please *accept this diff* and then in a stacked commit undo the change and wrap that code in `// clang-format off` and `// clang-format on`, or `/* clang-format off */` and `/* clang-format on */`. drop-conflicts Test Plan: sandcastleit Reviewed By: jerryzh168 Differential Revision: D22311706 fbshipit-source-id: 1ca59a82e96156a4a5dfad70ba3e64d44c5e762a
