Like this?

In addition to that the patch also enables all the 3 patterns for V2DImode
for -mxop too (all this depends on some solution for the vectorizable_shift
ICE I've posted yesterday) and except for the left shift xop only pattern
uses nonimmediate_operand on the last arg - even the xop pattern that start
with negation of the last operand can use nonimmediate_operand which
neg<mode>2 uses.

2011-10-28  Jakub Jelinek  <jakub@redhat.com>

	* config/i386/sse.md (VI4SD_AVX2): Removed.
	(VI48_AVX2, VI128_128, VI48_128, VI48_256): New mode iterators.
	(vashl<mode>3): Use VI12_128 iterator instead of VI124_128.
	Add another expander using VI48_128 iterator for
	TARGET_AVX2 || TARGET_XOP and another using VI48_256 iterator
	for TARGET_AVX2.
	(vlshr<mode>3): Likewise.  Change register_operand predicate to
	nonimmediate_operand on last operand in the VI12_128 expander.
	(vashr<mode>3): Use VI128_128 iterator instead of VI124_128.
	(vashrv4si3, vashrv8si3): New expanders.
	(avx2_ashrvv8si, avx2_ashrvv4si, avx2_<lshift>vv8si,
	avx2_<lshift>vv2di): Removed.
	(avx2_ashrv<mode>): New insn with VI4_AVX2 iterator.
	(avx2_<lshift>v<mode>): Macroize using VI48_AVX2
	iterator.  Simplify pattern.

	* gcc.dg/vshift-1.c: New test.
	* gcc.dg/vshift-2.c: New test.
	* gcc.target/i386/xop-vshift-1.c: New test.
	* gcc.target/i386/xop-vshift-2.c: New test.
	* gcc.target/i386/avx2-vshift-1.c: New test.

Yes.

I see some more cleanup opportunities with XOP patterns, I will try to
create a follow-up patch.
