RFT: HWPMC for powerpc -- G4+

[Justin Hibbits]

Attached you'll find a patch to add hwpmc support for MPC7450-series  
powerpc machines (later TiBooks, all AlBooks, Quicksilver and MDD  
towers, and mac mini).  It's not complete, but I want further testing  
while I finish up.  I've tested only counting PMCs, so don't know  
about sampling (pmcstat -S <something> doesn't seem to work, but I may  
be using it wrong), and will be adding exception support tomorrow  
which should make it more or less complete.
