MFC r258779,r258780,r258787,r258822:
Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this shifts into the sign bit. Instead use (1U << 31) which gets the expected result. Similar to the (1 << 31) case it is not defined to do (2 << 30). This fix is not ideal as it assumes a 32 bit int, but does fix the issue for most cases. A similar change was made in OpenBSD.
