vect: Add a function to check lane-reducing code
Check if an operation is lane-reducing requires comparison of code against
three kinds (DOT_PROD_EXPR/WIDEN_SUM_EXPR/SAD_EXPR). Add an utility
function to make source coding for the check handy and concise.

gcc/
* tree-vectorizer.h (lane_reducing_op_p): New function.
* tree-vect-slp.cc (vect_analyze_slp): Use new function
lane_reducing_op_p to check statement code.
* tree-vect-loop.cc (vect_transform_reduction): Likewise.
(vectorizable_reduction): Likewise, and change name of a local
variable that holds the result flag.
