*	X86: Do splat promotion later, so the optimizer can chew on it first.	Benjamin Kramer	2013-01-26
\| \| \| \| \| \| \| \| \| \| \| \|	This catches many cases where we can emit a more efficient shuffle for a specific mask or when the mask contains undefs. Once the splat is lowered to unpacks we can't do that anymore. There is a possibility of moving the promotion after pshufb matching, but I'm not sure if pshufb with a mask loaded from memory is faster than 3 shuffles, so I avoided that for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173569 91177308-0d34-0410-b5e6-96231b3b80d8
