Note, I will be away on vacation from Tuesday February 25th through Friday
March 7th. At this point of time, I do not anticipate bringing a laptop that I
can respond to emails on this account.

Previously GCC would zero externd a DImode GPR value to TImode by first zero
extending the DImode value into a GPR TImode value, and then do a MTVSRDD to
move this value to a VSX register.
This patch does the move directly, since if the middle argument to MTVSRDD is 0,
it does the zero extend.
