Summary: The .clang-tidy file is copied from the top-level LLVM source directory. Also fix warnings generated by clang-format: * Moved SimpleHostPlatformDevice.h so its header include guard could have the right format. * Changed signatures of methods taking llvm::Twine by value to take it by const ref instead. * Add "noexcept" to some move constructors and assignment operators. * Removed a bunch of places where single-statement loops and conditionals were surrounded with braces. (This was not found by the current clang-tidy, but with a local patch that I hope to upstream soon.)
