c++: Better module initializer code
Every module interface needs to emit a global initializer, but it
might have nothing to init. In those cases, there's no need for any
idempotency boolean to be emitted.
gcc/cp
* cp-tree.h (module_initializer_kind): Replace with ...
(module_global_init_needed, module_has_import_inits): ...
these.
* decl2.cc (start_objects): Add has_body parm. Reorganize
module initializer creation.
(generate_ctor_or_dtor_function): Adjust.
(c_parse_final_cleanups): Adjust.
(vtv_start_verification_constructor_init_function): Adjust.
* module.cc (module_initializer_kind): Replace with ...
(module_global_init_needed, module_has_import_inits): ...
these.
gcc/testsuite/
* g++.dg/modules/init-2_a.C: Check no idempotency.
* g++.dg/modules/init-2_b.C: Check idempotency.
