Allow-list unsigned integer overflows.
This CL adds the 'no_sanitize("unsigned-integer-overflow")' Clang/LLVM
attribute to several locations that intentionally rely on that behavior.
From https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html: "this
is not undefined behavior, but it is often unintentional." By using an
explicit allow-list, we should still be able to detect the latter case.
