Language: parent::class outside class scope — wrong compile fatal message (zend_compile.c)

Problem

Using parent::class at file scope must be rejected at compile time. Zend reports:

Cannot use "parent" in the global scope

This compiler emits a misleading fatal:

self:: used outside of class scope

php-src reference

• php/php-src Zend/zend_compile.c — parent / self / static scope checks for ::class

Repro

test/repro-maintainer/parity_parent_class_global.php:

<?php
class C extends stdClass {}
echo parent::class;

./script/docker-exec.sh -- bash -lc 'php bin/vm.php test/repro-maintainer/parity_parent_class_global.php 2>&1 | head -5'

Expected: compile/runtime fatal mentioning parent / global scope (Zend wording).
Actual: self:: used outside of class scope.

Acceptance

• Fatal text matches Zend for parent:: / self:: / static:: pseudo-constants used outside allowed scope.
• Compliance .phpt comparing message substring.

Merged via #5027.

Verification: compile-time fatal Cannot use "parent" in the global scope (and matching messages for self / static) at file scope; issue repro + PseudoClassGlobalScopeCompileTest + compliance pseudo_class_global_scope.phpt green on VM.
