Opto: hook to postprocess matcher output platform dependent.

On Power we need to add a special input, the toc, to
nodes loading constants. This must happen after matching,
but before register allocation.
This change adds a class PdCompile which contains a method
pd_post_matching_hook() on each platform. The method is
- so far - empty everywhere. It's called in compile() after
matching.
