Description:
------------
As far as I understand from the documentation setting ASSERT_QUIET_EVAL / assert.quiet_eval to 1 should suppress any error message triggered when evaluating an assertion. 
Either this is not the case or I misunderstand the (rather scarce) documentation on this option. 

Test script:
---------------
<?php
error_reporting(E_ALL);

assert_options(ASSERT_QUIET_EVAL, 1);
assert($foo);

Expected result:
----------------
Warning: assert(): assert($foo) failed in […] on line 5


Actual result:
--------------
Notice: Undefined variable: foo in […] on line 5

Warning: assert(): assert($foo) failed in […] on line 5

ASSERT_QUIET_EVAL only works if assert() is called on a string;
cf. <https://3v4l.org/k2rbK>. It seems to me that the
documentation has to be improved, and also that ASSERT_QUIET_EVAL
(and maybe other assert_options) should have been deprecated in
PHP 7.2 (where calling assert() with a string argument) has been
deprecated).

@cmb: As we don't really have a concept of deprecation for constants (though maybe we should add one...) we should probably just drop these when we drop support for string asserts in PHP 8, as they will no longer do anything.

Actually, I was like the reporter: expecting this to have effect when using PHP7-style assertions.

```php
ini_set('assert.quiet_eval', '1');
set_error_handler(function () { echo error_reporting(); });
assert(false);
```

This should echo "0" to me.
That's what we'd all understand by reading the doc, and what is the most useful.
Can we consider fixing this behavior?

ASSERT_QUIET_EVAL has been removed in PHP 8, so closing this issue.
