Summary: Adding support for -print-module-scope similar to how it is being done for function passes. This option causes loop-pass printer to emit a whole-module IR instead of just a loop itself.

; This test checks -print-after/before on loop passes

; Besides of the loop itself it should be dumping loop pre-header and exits.
