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.

; Test ensures that non-optimizable array mallocs are not optimized; specifically
|
|
; GlobalOpt was treating a non-optimizable array malloc as a non-array malloc
|
|
; and optimizing the global object that the malloc was stored to as a single
|
|
; element global. The global object @TOP in this test should not be optimized.
