tree-vect-loop.c (vect_determine_vectorization_factor): Handle both pattern and original statements if necessary.
* tree-vect-loop.c (vect_determine_vectorization_factor): Handle
both pattern and original statements if necessary.
(vect_transform_loop): Likewise.
* tree-vect-patterns.c (vect_pattern_recog): Update documentation.
* tree-vect-stmts.c (vect_mark_relevant): Add new argument.
Mark the pattern statement only if the original statement doesn't
have its own uses.
(process_use): Call vect_mark_relevant with additional parameter.
(vect_mark_stmts_to_be_vectorized): Likewise.
(vect_get_vec_def_for_operand): Use vectorized pattern statement.
(vect_analyze_stmt): Handle both pattern and original statements
if necessary.
(vect_transform_stmt): Don't store vectorized pattern statement
in the original statement.
(vect_is_simple_use_1): Use related pattern statement only if the
original statement is irrelevant.
* tree-vect-slp.c (vect_get_and_check_slp_defs): Likewise.
