Hmm, there are some interesting differences in the behaviour of the two patches.
My patch allows cse to remove the dead calls to link_error*. With Fariborz's
patch, the calls stay until combine cleans things up. Also, -O1 code is better
with my patch as it allows life analysis to remove stores to i[0..7].
