[ConstraintElim] Remove dead compares after simplification.
Remove compares after replacing all uses. Cleaning dead compares can
enable additional simplifications when adjusting the position of the
pass slightly. In particular, it seems like the additional dead
instructions may prevent SimplifyCFG performing some folds.

[ConstraintElim] Track and simplify conditions at use.
This patch updates ConstraintElimination to track uses of conditions in
the worklist. This allows simplifying conditions using the context that
holds directly at the condition, instead of where the condition is
defined.
This allows us to catch more cases in practice: there are multiple
code-size changes for CTMark while compile-time remains unchanged:

This should help to simplify D151799.
