i386: Expand mul<VI8_AVX2> earlier
Move the expansion code to i386.c next to mulv4si3. Eliminate
one shift by adding the highparts before shifting. Correct costs.
* config/i386/sse.md (mul<VI8_AVX2>3): Change from insn_and_split
to expander; move guts to ...
* config/i386/i386.c (ix86_expand_sse2_mulvxdi3): ... here. Add
highparts before shifting up.
* config/i386/i386-protos.h: Update.
