This moves the old pass creation functionality to its own header and updates the callers of that routine. Then it adds a new PM supporting bitcode writer to the header file, and wires that up in the opt tool. A test is added that round-trips code into bitcode and back out using the new pass manager. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199078 91177308-0d34-0410-b5e6-96231b3b80d8

; 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.
