Modified Files:
        src/sys/arch/powerpc/include: altivec.h fpu.h pcb.h
        src/sys/arch/powerpc/oea: altivec.c
        src/sys/arch/powerpc/powerpc: fpu.c process_machdep.c sig_machdep.c
            trap.c vm_machdep.c

Log Message:
Add a SAVE/DISCARD flag to save_{fpu,vec}_lwp.  Use it appropriately.
Nuke struct fpu and use struct fpreg instead (except for the names, they
were identical).  On MP machines, this will avoid an unneeded IPI to save
the register contents that are about to discarded.
