  [GVN] introduce GVNOptions to control GVN pass behavior

There are a few global (cl::opt) controls that enable optional
behavior in GVN. Introduce GVNOptions that provide corresponding
per-pass instance controls.

That will allow to use GVN multiple times in pipeline each time
with different settings.
