  Log Message:
  -----------
  [Wunsafe-buffer-usage] False positives for & expression indexing constant size array (arr[anything & 0]) (#112284)

Do not warn when a constant sized array is indexed with an expression
that contains bitwise and operation
involving constants and it always results in a bound safe access.
