predicates.md (general_vector_operand): New predicate.

	* config/i386/predicates.md (general_vector_operand): New predicate.
	* config/i386/i386.c (const_vector_equal_evenodd_p): New function.
	(ix86_expand_mul_widen_evenodd): Force op1 resp. op2 into register
	if they aren't nonimmediate operands.  If their original values
	satisfy const_vector_equal_evenodd_p, don't shift them.
	* config/i386/sse.md (mul<mode>3): Use general_vector_operand
	predicates.  For the SSE4.1 case force operands[{1,2}] into registers
	if not nonimmediate_operand.
	(vec_widen_smult_even_v4si): Use nonimmediate_operand predicates
	instead of register_operand.
	(vec_widen_<s>mult_odd_<mode>): Use general_vector_operand predicates.
