RFA: rs6000: Fix type conversion in __ev_set_acc_{s|u}64

[Nick Clifton]

Hi Aldy,

  Please can I apply the patch below.  It fixes the __ev_set_acc_s64
  and __ev_set_acc_u64 macros in the spe.h header to perform explicit
  type conversion, rather than replying upon C's automatic
  conversions, which do not work when vectors are involved.

Cheers
        Nick

	* config/rs6000/spe.h (__ev_set_acc_u64): Use __ev_create_u64 to
	convert uint64_t into __ev64_opaque__.
	(__ev_set_acc_s64): Likewise, but using signed types.
