+ added ppc740 (g3), ppc7400 (G4) and ppc970 (G5) as ppc32 cpu
targets
* initialise optimizecputype by default to ppc7400 for ppc32 and to
ppc970 for ppc64
* merged ppc32/ppc64 overflow checking code and use the ppc64 one
in case cputype or optimizecputype >= ppc970, because one of
the instructions used in the ppc32 version no longer exists on the
ppc970 (although it's emulated in the kernel on at least Mac OS X)
* moved some other support routines and constants to ppcgen which
were needed for the overflow checking (were identical for ppc32 and
ppc64)
