some integer undefined behaviors in gcc

[John Regehr <regehr at cs dot utah dot edu>]

I ran gcc 162830 on x86 under a tool that checks for integer undefined
behaviors.  The attached error messages show up when running "make
check" and when recompiling gcc.

Each line in the attachment is an error message giving the problematic
operator, its srcloc, the types of its operands, and examples of
offending values.

Let me know if more detail is needed or if it would be better for me to
file all 71 bug reports.

Thanks,

John Regehr
