Chris Lattner 4fbb612685 Handle cracked instructions in dispatch group formation.
llvm-svn: 26721

Chris Lattner 51348c5f27 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.

Nate Begeman 3e3219cc0a This kinda sorta implements "things that have to lead a dispatch group".

Chris Lattner 2cab13573c Implement a very very simple hazard recognizer for LSU rejects and ctr set/read
flushes
