* config/i386/sse.md (vec_extract_lo_<mode><mask_name>): For
V8FI, V16FI and VI8F_256 iterators, use <store_mask_predicate> instead
of nonimmediate_operand and <store_mask_constraint> instead of m for
the input operand. For V8FI iterator, always split if input is a MEM.
For V16FI and V8SF_256 iterators, don't test if both operands are MEM
if <mask_applied>. For VI4F_256 iterator, use <store_mask_predicate>
instead of register_operand and <store_mask_constraint> instead of v
for
the input operand. Make sure both operands aren't MEMs for if not
<mask_applied>.
