I have now checked in the hybrid EVRP pass.

I made some minor tweaks. the option to the new -fevrp-mode flag are now:
legacy : classic EVRP mode
ranger : Ranger only mode
*legacy-first : Query ranges with EVRP first, and if that fails try
the ranger*
ranger-first : Query the ranger first, then evrp
ranger-trace : Ranger-only mode plus Show range tracing info in the dump
ranger-debug : Ranger-only mode, and also include all cache debugging info
trace : Hybrid mode with range tracing info
debug : Hybrid mode with cache debugging as well as tracing
The default is still *legacy-first*.
We'll have to keep -fevrp-mode forever so can you instead make it a --param
since I hope it is transitional only? It certainly shouldn't be a
user-visible flag, should it?
Richard.
doesnt need to be user visible, just to give us the ability to turn
things on and off.
Sure. I'll try to get to that shortly.
