This reverts commit 10b09578a8.
This seems to cause many test failures:

Test <=> operator : different types [tests/lang/operators/operator_spaceship_basic.phpt]
comparing different variables for equality [Zend/tests/compare_001_64bit.phpt]
comparing different variables for identity [Zend/tests/compare_002_64bit.phpt]
Rebinding of ::getClosure()s [Zend/tests/closure_061.phpt]
comparing different variables (greater than) [Zend/tests/compare_003_64bit.phpt]
comparing different variables (less than) [Zend/tests/compare_004_64bit.phpt]
comparing different variables (greater or equal than) [Zend/tests/compare_005_64bit.phpt]
comparing different variables (smaller or equal than) [Zend/tests/compare_006_64bit.phpt]
Invalid numeric string E_WARNINGs and E_NOTICEs, combined assignment operations [Zend/tests/numeric_string_errors_assign.phpt]
Bug #51819 (Case discrepancy in timezone names cause Uncaught exception and fatal error) [ext/date/tests/bug51819.phpt]
Test all filters returned by filter_list() [ext/filter/tests/033.phpt]
filter_var() and FILTER_VALIDATE_MAC [ext/filter/tests/055.phpt]
Test strrpos() function : usage variations - unexpected inputs for 'needle' argument [ext/standard/tests/strings/strrpos_variation10.phpt]
Test strtr() function : usage variations - empty string & null for 'str' argument [ext/standard/tests/strings/strtr_variation4.phpt]
Test strtr() function : usage variations - unexpected inputs for 'from' argument [ext/standard/tests/strings/strtr_variation6.phpt]
