rsx/fp: Improvements

Browse Source 
- Export some debug information in the free texture register space components zw
  Very useful when analysing renderdoc captures
- Enable shadow comparison on depth as long as compare function is active and texture is uploaded for depth read
  Some engines (UE3) read all the components in the shader and use mul/mad with the result
