lookup if set->vars is shared. Don't keep slot cleared before

* c-common.c (c_common_attribute_table): Allow
handle_visibility_attribute to be called for types.
(handle_visibility_attribute) When given a type, set the visibility
bits on the TYPE_NAME. When given a decl, don't set no_add_attrs
so that we can check later whether the attribute was present. Added
warning if attribute applied to non class type.
* c-decl.c (diagnose_mismatched_decls): Updated rules for merging
decls and checking that they are consistent.
* common.opt: Added -fvisibility.
* c.opt, c-opts.c: Added -fvisibility-inlines-hidden.
* c-pragma.h, c-pragma.c: Added handle_pragma_visibility().
* flags.h, tree.h: Added assorted support defines for overall patch
* opts.c: Added parsing support for -fvisibility.
* tree.c (build_decl): Set visibility for all decls to be whatever

* varasm.c (default_binds_local_p_1): Reworked logic determining

* decl.c (duplicate_decls): New logic for merging definition decls
with declaration decls. Added ignore & warning when non default
