separate load of use_retva into SSA_NAME and then store of it
into gimple_call_lhs (stmt).

* gcc.dg/plugin/analyzer_cpython_plugin.cc: Move everything from
namespace ana:: into ana::cpython_plugin. Move global tree values
into a new "class api".
(pyobj_record): Replace with api.m_type_PyObject.
(pyobj_ptr_tree): Replace with api.m_type_PyObject_ptr.
(pyobj_ptr_ptr): Replace with api.m_type_PyObject_ptr_ptr.
(varobj_record): Replace with api.m_type_PyVarObject.
(pylistobj_record): Replace with api.m_type_PyListObject.
(pylongobj_record): Replace with api.m_type_PyLongObject.
(pylongtype_vardecl): Replace with api.m_vardecl_PyLong_Type.
(pylisttype_vardecl): Replace with api.m_vardecl_PyList_Type.
(get_field_by_name): Add "complain" param and use it to issue a
note on failure. Assert that type and name are non-null. Don't
crash on fields that are anonymous unions, and special-case
looking within them for "ob_refcnt" to work around the
Python 3.11 change for PEP 683 (immortal objects).
(get_sizeof_pyobjptr): Convert to...
(api::get_sval_sizeof_PyObject_ptr): ...this
(init_ob_refcnt_field): Convert to...
(api::init_ob_refcnt_field): ...this.
(set_ob_type_field): Convert to...
(api::set_ob_type_field): ..this.
(api::init_PyObject_HEAD): New.
(api::get_region_PyObject_ob_refcnt): New.
(api::do_Py_INCREF): New.
(api::get_region_PyVarObject_ob_size): New.
(api::get_region_PyLongObject_ob_digit): New.
(inc_field_val): Convert to...
(api::inc_field_val): ...this.
(refcnt_mismatch::refcnt_mismatch): Add tree params for refcounts
and initialize corresponding fields. Fix whitespace.
(refcnt_mismatch::emit): Use stored tree values, rather than
assuming we have constants, and crashing non-constants. Delete
commented-out dead code.
(refcnt_mismatch::foo): Delete.
(refcnt_mismatch::m_expected_refcnt_tree): New field.
(refcnt_mismatch::m_actual_refcnt_tree): New field.
(retrieve_ob_refcnt_sval): Simplify using class api.
(count_pyobj_references): Likewise.
(check_refcnt): Likewise. Don't warn on UNKNOWN values. Use
get_representative_tree for the expected and actual values and
skip the warning if it fails, rather than assuming we have
constants and crashing on non-constants.
(count_all_references): Update comment.
(kf_PyList_Append::impl_call_pre): Simplify using class api.
(kf_PyList_Append::impl_call_post): Likewise.
(kf_PyList_New::impl_call_post): Likewise.
(kf_PyLong_FromLong::impl_call_post): Likewise.
(get_stashed_type_by_name): Emit note if the type couldn't be
found.
(get_stashed_global_var_by_name): Likewise for globals.
(init_py_structs): Convert to...
(api::init_from_stashed_types): ...this. Bail out with an error
code if anything fails. Look up more things at startup, rather
than during analysis of calls.
(ana::cpython_analyzer_events_subscriber): Rename to...
(ana::cpython_plugin::analyzer_events_subscriber): ...this.
(analyzer_events_subscriber::analyzer_events_subscriber):
Initialize m_init_failed.
(analyzer_events_subscriber::on_message<on_tu_finished>):
Update for conversion of init_py_structs to
api::init_from_stashed_types and bail if it fails.
(analyzer_events_subscriber::on_message<on_frame_popped): Don't
run if plugin initialization failed.
(analyzer_events_subscriber::m_init_failed): New field.
