Several big changes:
...
1. Use flags on the instructions in the .td file to indicate the PPC970 unit
type instead of a table in the .cpp file. Much cleaner.
2. Change the hazard recognizer to build d-groups according to the actual
algorithm used, not my flawed understanding of it.
3. Model "must be in the first slot" and "must be the only instr in a group"
accurately.

This kinda sorta implements "things that have to lead a dispatch group".

add some new instructions to the classifier. With this, we correctly insert

a nop into Freebench/neural, which speeds it up from 136->129s (~5.4%).
