Thoughts on using both patches to ensure the we don't have extraneous

Maybe we should add all stores to the KILL set
for a sibling call and not worry about whether
they are frame related or not.
For a sibling call, that may not be a terrible idea. We're not really
able to track the frame/arg pointer stuff well in that case and once
those are off the table, there's not much benefit in tracking stuff for
sibcalls.
