i386: Simplify {,v}ph{add,sub{,s}{w,d} insn patterns [PR94460]
As mentioned in the previous PR94460 patch, the RTL patterns look too
large/complicated, we can simplify them by just performing two 2 arg
permutations to move the arguments into the right spots and then just
doing the plus/minus (or signed saturation version thereof).
