re PR tree-optimization/51000 (ICE: in vect_get_store_cost, at tree-vect-stmts.c:923 on powerpc-apple-darwin9)
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.
