Reopening as this patch had to reverted as it caused a bootstrap failure on
ppc-darwin. I think there
really is a latent bug with -1 - A being converted to ~A and then ~A is
constant folded to -1 but it
contains a TREE_OVERFLOW bit turned on which it did not with -1 - A before.
(there might be some
unsignedness going on that I don't know about).
