tree-optimization/102847 - properly cost VMAT_INVARIANT loads

The following adds proper costing of VMAT_INVARIANT loads, avoiding
to ask the target about the cost of an unsupported vector load cost
which we won't emit anyway.

PR tree-optimization/102847
* tree-vect-stmts.c (vect_model_load_cost): Explicitely
handle VMAT_INVARIANT as a splat in the prologue.
