r256543:
Add fasttrap for PowerPC. This is the last piece of the DTrace/ppc puzzle. It's incomplete, it doesn't contain full instruction emulation, but it should be sufficient for most cases.
r259245,r259421: (FBT)
FBT now does work fully on PowerPC.
Save r3 before using it for the trap check, else we end up saving the new r3, containing the trap instruction encoding (0x7c810808), and restoring it back with the frame on return. This caused it to panic on my ppc32 machine.
r259668,r259674: Fix a typo in the FBT code.

Add FBT for PowerPC DTrace. Also, clean up the DTrace assembly code, much of which is not necessary for PowerPC.
The FBT module can likely be factored into 3 separate files: common, intel, and powerpc, rather than duplicating most of the code between the x86 and PowerPC flavors.
All DTrace modules for PowerPC will be MFC'd together once Fasttrap is completed.
