* common.opt (ftree-vectorize): No longer set flag_tree_vectorize.
(ftree-loop-vectorize): Set as EnabledBy ftree-vectorize.
(ftree-slp-vectorize): Likewise.
* omp-expand (expand_omp_simd): Remove flag_tree_vectorize, as it
can no longer be set independent of flag_tree_loop_vectorize.
* omp-general.c (emp_max_vf): Likewise.
* opts.c (enable_fdo_optimizations): Remove references to
flag_tree_vectorize, these are now implicit.
(common_handle_option): Remove handling for OPT_ftree_vectorize,
and leave it for the options machinery.
