Hi Eric, no, I don't, but all these instances are related in the sense that
they all show missed optimizations for dead code. Instead of filing them
separately, I thought it might work better if I file them together as a meta
issue.=20

If you folks prefer these being filed separately, I'm also happy to do so.=
=20

Please just let me know whichever works better; thanks.=20
