Assertion when fetching property of "bad" magic constant

### Description

The following code:

```php
<?php
const C = __file__->foo;
```

Resulted in this output:
```
zend_compile.c:9852: zend_compile_const_expr_magic_const: Assertion `ast->attr == T_CLASS_C' failed.
```

But I expected this output instead:
```
Fatal error: Constant expression contains invalid operations
```
