Move EXTRACT_LAST_REDUCTION costing to vectorizable_condition
gcc.target/aarch64/sve/clastb_[57].c started failing after the increase
in the cost of vec_to_scalar (r278452). The problem is that we were
double-counting the cost of the CLASTB: once in vect_model_reduction_cost
as a vec_to_scalar and once in vectorizable_condition as a plain
vector_stmt.
Based on the TODO above vect_model_reduction_cost, I think the
preferred long-term direction is for vectorizable_* to cost these
things itself, so that's what the patch does (for this one case only).

gcc/
* tree-vect-stmts.c (vect_model_simple_cost): Take an optional
vect_cost_for_stmt.
(vectorizable_condition): Calculate the cost of EXTRACT_LAST_REDUCTION
here rather than...
* tree-vect-loop.c (vect_model_reduction_cost): ...here.
