PR tree-optimization/49352
* tree-vect-loop.c (vect_is_slp_reduction): Don't count debug
uses at all, make sure loop_use_stmt after the loop is a def
stmt of a used SSA_NAME that is the only one defined inside
of the loop.  Don't check for COND_EXPR and GIMPLE_BINARY_RHS.
(vect_is_simple_reduction_1): Call vect_is_slp_reduction only
if check_reduction is true.
