const int *	opmap
const unsigned int	num_slp_children

Detailed Description

Helper class for mapping of GIMPLE operands to SLP children.   

???  Add vect_slp_child_index_for_operand here and amend opmaps
with the full reverse mapping and indicating the position of the
first commutative operand index, eliding the swap_p argument from
vect_get_operand_map.  Adjust all consumers.
