PR middle-end/64313
* tree-core.h (builtin_info, builtin_info_type): Turn from
an object with two arrays into an array of an object with
decl and two flags, implicit_p and declared_p.
* tree.h (builtin_decl_explicit, builtin_decl_implicit,
set_builtin_decl, set_builtin_decl_implicit_p,
builtin_decl_explicit_p, builtin_decl_implicit_p): Adjust.
(set_builtin_decl_declared_p, builtin_decl_declared_p): New functions.
* builtins.c (builtin_info): Adjust.
* gimplify.c (gimplify_addr_expr): References to builtins
that have been declared by the user makes them eligible for
use by the compiler. Call set_builtin_decl_implicit_p on them.
c/
* c-decl.c (merge_decls): Call set_builtin_decl_declared_p
for builtins the user declared correctly.
cp/
* decl.c (duplicate_decls): Call set_builtin_decl_declared_p
for builtins the user declared correctly.
