* tree-vect-stmts.c (vect_mark_relevant): Only use
FOR_EACH_IMM_USE_FAST if lhs is SSA_NAME.
(vectorizable_store): If is_pattern_stmt_p look through
VIEW_CONVERT_EXPR on lhs.
* tree-vect-patterns.c (check_bool_pattern, adjust_bool_pattern):
Use unsigned type instead of signed.
(vect_recog_bool_pattern): Optimize also stores into bool memory in
addition to casts from bool to integral types.
(vect_mark_pattern_stmts): If pattern_stmt already has vinfo
created, don't create it again.
* gcc.dg/vect/vect-cond-10.c: New test.
Looking at gfortran.dg/alloc_comp_assign_2.f90, the original data-refs were in
an interleaving group, so only the first store had to be aligned. The pattern
data-refs are not marked as in interleaving group, so there are 3 unsupported
unaligned stores now.
