Print Pass Names

Currently, when we print the passes it does not print its name. This becomes confusing when we want to print all the passes at once (e.g., -fdump-tree-all-all=stderr &> pass.dump).
This patch adds functionality to print the pass name. It passes bootstrap (with default configurations).

Hope this is useful.

Thanks,
-Aditya

Can't you just use current_pass->name?
