r600g: simplify flushing

Browse source 
Based on the patch called "simplify and fix flushing and synchronization"
by Jerome Glisse.

Rebased, removed unneded code, simplified more and cleaned up.

Also, SH_ACTION_ENA is not set when changing shaders (hw doesn't seem
to need it). It's only used to flush constant buffers.
