[08/46] Add vec_info::lookup_def
This patch adds a vec_info helper for checking whether an operand is an
SSA_NAME that is defined in the vectorisable region.

* tree-vect-loop.c (vect_analyze_loop_operations): Likewise.
(vectorizable_reduction): Likewise.
(vect_valid_reduction_input_p): Take a stmt_vec_info instead
of a gimple *.
(vect_is_slp_reduction): Update calls accordingly. Use
vec_info::lookup_def.
(vect_is_simple_reduction): Likewise
