[llvm-dev] Removing DeadInstEliminationPass

DeadInstEliminationPass is like DeadCodeEliminationPass but it only does
one pass through a function instead of iterating on users of eliminated

The reason I'd like to remove this is because it isn't ported to the new
pass manager, and it doesn't seem very useful when DeadCodeEliminationPass
exists. It also doesn't have very many appearances in tests compared to DCE.

Removing in https://reviews.llvm.org/D87933

Any objections?
