    [bigint] Fix harmless DCHECK failure · a6ab4e00
    Jakob Kummerow authored
    Behavior in Release mode was correct; Debug mode triggered a DCHECK
    failure that indicated an inefficiency: when a requested truncation
    would be a no-op, we should return the original BigInt, rather than
    creating a copy. In the special case of -2^(n-1), i.e. the smallest
    negative n-bit integer, getting truncated to n bits, with n being a
    multiple of kDigitBits, this shortcut was not taken.
