Andrew Trick 20151da8c3 [disable-iv-rewrite] Allow WidenIV to handle NSW/NUW operations
better.

Don't immediately give up when an add operation can't be trivially
sign/zero-extended within a loop. If it has NSW/NUW flags, generate a
new expression with sign extended (non-recurrent) operand. As before,
if SCEV says that all sign extends are loop invariant, then we can
widen the operation.
