[PowerPC] Reject tdescs with VSX and no FPU or Altivec
Currently rs6000_gdbarch_init will accept a tdesc with the
"org.gnu.gdb.power.vsx" feature but without the
"org.gnu.gdb.power.altivec" or "org.gnu.gdb.power.fpu".
It isn't clear from the standard features documentation that these are
requirements. However, these tdescs would cause trouble in the VSX
pseudo-register functions, so this patch will cause them to be
rejected.

* rs6000-tdep.c (rs6000_gdbarch_init): Reject tdescs with vsx but
without altivec or fpu.
