New Revision: 181250

Log:
    PR tree-optimization/51000
    * tree-vect-patterns.c (vect_recog_bool_pattern): If adding
    a pattern stmt for a bool store, adjust DR_STMT too.
    Don't handle bool conversions to single bit precision lhs.
    * tree-vect-stmts.c (vect_remove_stores): If next is a pattern
    stmt, remove its related stmt and free its stmt_vinfo.
    (free_stmt_vec_info): Free also pattern stmt's vinfo and
    pattern def stmt's vinfo.
    * tree-vect-loop.c (destroy_loop_vec_info): Don't try to
    free pattern stmt's vinfo here.
    (vect_transform_loop): When calling vect_remove_stores,
    do gsi_next first and don't call gsi_remove.  If not strided
    store, free stmt vinfo for gsi_stmt (si) rather than stmt.

    * gcc.dg/vect/pr51000.c: New test.
