This patch changes the -fopt-info default to optimized instead of all,
since the latter is extremely verbose. This reduced the -fopt-info output by
over 75% in at least one case, since the vectorizer has many messages under
MSG_NOTE (and that should grow as more passes are converted to the new dump
infrastructure). The default now emits high-level optimization success info
(currently for unrolling, inlining and vectorization).
Also changed which vectorization summary messages are emitted under
-fopt-info(=optimized), to be more consistent with the format of the
optimization summary messages emitted by the unroller and inliner,
and fixed the loop vectorization summary message to use dump_printf_loc
instead of manually emitting the location info.
Bootstrapped and tested on x86-64-unknown-linux-gnu. Ok for trunk?

* dumpfile.c (opt_info_switch_p): Change -fopt-info
default to -fopt-info=optimized instead of all.
* doc/invoke.texi: Ditto.
* tree-vectorizer.c (vectorize_loops): Emit loop vectorization
success under MSG_ALL, and use dump_printf_loc.
(execute_vect_slp): Emit BB vectorization success under
MSG_OPTIMIZED_LOCATIONS.
* tree-vect-slp.c (vect_make_slp_decision): Ditto.
(vect_slp_transform_bb): Change MSG_OPTIMIZED_LOCATIONS
to MSG_NOTE.
* tree-vect-loop.c (vect_transform_loop): Ditto.
