re PR target/70021 (Test miscompiled with -O3 option for -march=core-avx2.)
PR target/70021
* tree-vect-stmts.c (vect_mark_relevant): Remove USED_IN_PATTERN
argument, if STMT_VINFO_IN_PATTERN_P (stmt_info), always mark
the pattern no matter if it is used just by non-pattern, pattern
or mix thereof.
(process_use, vect_mark_stmts_to_be_vectorized): Adjust callers.
* tree-vect-patterns.c (vect_recog_vector_vector_shift_pattern): If
oprnd1 def_stmt is in pattern, don't look through it.
* gcc.dg/vect/pr70021.c: New test.
* gcc.target/i386/pr70021.c: New test.
