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.
