Florian Hahn	13ffde316a	[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] 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.

[test] Use -passes syntax when specifying pipeline in some more tests

The legacy PM is deprecated, so update a bunch of lit tests running
opt to use the new PM syntax when specifying the pipeline.
In this patch focus has been put on test cases for ConstantMerge,
ConstraintElimination, CorrelatedValuePropagation, GlobalDCE,
GlobalOpt, SCCP, TailCallElim and PredicateInfo.

[ConstraintElimination] Extend test coverage.

This patch adds a lot of additional tests, focusing on loops and GEP
arithmetic. Some of the tests expose existing problems, which will be
fixed soon.
