[PATCH] Fix PR 52199 on power7 (VEC_DUPLICATE)


This patch fixes PR 52199, which shows up on power7 systems when the compiler
is vectorizing DImode operations, and the vector duplicate code was not
prepared to accept CONST and SYMBOL_REF's.

I have done a bootstrap and make compare, and there were no regressions.  Is
this ok to install?  I will also back port the change to 4.6, since the exact
same code is in that revision as well.
