[Mesa-dev] intel: release build compile warnings cleanups

[Eric Anholt]

I got tired of freaking out a little every time I built my release tree
because of compile warnings.  All but the last 2 seemed like pretty clean
fixes to me.

And then there's the first patch, which is unrelated but I found while
trying to figure out why register_coalesce() does something that
opt_copy_propagate() doesn't.

Available at compile-warnings of my tree.
