[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. gdb/ChangeLog: 2018-10-26 Pedro Franco de Carvalho <pedromfc@linux.ibm.com> * rs6000-tdep.c (rs6000_gdbarch_init): Reject tdescs with vsx but without altivec or fpu.
