| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26719 91177308-0d34-0410-b5e6-96231b3b80d8

This reduces the memory usage for the testcase in PR681 from 496 to 26MB of ram on my darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a 2.5GHz G5.
