Darwin, PPC : Fix R13 for PPC64.

We have a somewhat unusual situation in that for PPC64, R13 is
both reserved and callee-saved (it is used internally by the
pthreads implementation to contain pthread_self).

So add R13 to the fixed regs, but also keep it in the callee-
saved set.

gcc/ChangeLog:

* config/rs6000/darwin.h (FIXED_R13): Add for PPC64.
(FIRST_SAVED_GP_REGNO): Save from R13 even when it is one
of the fixed regs.

(cherry picked from commit b12d6e79899fd27833c53ffc3c973538244f62e1)
