Subject: [PATCH] Storing an out of range constant into a variable should
 ideally cause the compiler to give an error.  Right now 6g warns about large
 shifts but does not give an error.  This CL removes the out of range shift
 from shift.go, so that it will work with gccgo, and adds a test case in bugs/
 to be fixed at a later date.
