__builtin_dynamic_object_size: Recognize builtin
Recognize the __builtin_dynamic_object_size builtin and add paths in the
object size path to deal with it, but treat it like
__builtin_object_size for now. Also add tests to provide the same
testing coverage for the new builtin name.
gcc/ChangeLog:
* builtins.def (BUILT_IN_DYNAMIC_OBJECT_SIZE): New builtin.
* tree-object-size.h: Move object size type bits enum from
tree-object-size.c and add new value OST_DYNAMIC.
* builtins.c (expand_builtin, fold_builtin_2): Handle it.
(fold_builtin_object_size): Handle new builtin and adjust for
change to compute_builtin_object_size.
* tree-object-size.c: Include builtins.h.
(compute_builtin_object_size): Adjust.
(early_object_sizes_execute_one,
dynamic_object_sizes_execute_one): New functions.
(object_sizes_execute): Rename insert_min_max_p argument to
early. Handle BUILT_IN_DYNAMIC_OBJECT_SIZE and call the new
functions.
* doc/extend.texi (__builtin_dynamic_object_size): Document new
builtin.
