Chandler Carruth 1d9ab25560 [PM] Wire up the Verifier for the new pass manager and connect it to the
various opt verifier commandline options.

Mostly mechanical wiring of the verifier to the new pass manager.
Exercises one of the more unusual aspects of it -- a pass can be either
a module or function pass interchangably. If this is ever problematic,
we can make things more constrained, but for things like the verifier
where there is an "obvious" applicability at both levels, it seems
convenient.

This is the next-to-last piece of basic functionality left to make the
opt commandline driving of the new pass manager minimally functional for
testing and further development. There is still a lot to be done there
(notably the factoring into .def files to kill the current boilerplate
code) but it is relatively uninteresting. The only interesting bit left
for minimal functionality is supporting the registration of analyses.
I'm planning on doing that on top of the .def file switch mostly because
the boilerplate for the analyses would be significantly worse.

; This test is essentially doing very basic things with the opt tool and the
; new pass manager pipeline. It will be used to flesh out the feature
; completeness of the opt tool when the new pass manager is engaged. The tests
; may not be useful once it becomes the default or may get spread out into other
; files, but for now this is just going to step the new process through its
; paces.
