tree-optimization/101083 - fix ICE with SLP reassoc

SLP node build rather than picking that from operand one which,
when constant or external, could be NULL.

PR tree-optimization/101083
* tree-vect-slp.c (vect_slp_build_two_operator_nodes): Get
vectype as argument.
(vect_build_slp_tree_2): Adjust.
* gcc.dg/vect/pr97832-4.c: New testcase.
