Speed up ZEND_SWITCH_STRING/ZEND_SWITCH_LONG for wrong type

This has the minor benefit of avoiding loading the address of the
jump table when the expression for the switch isn't a string/long.
gcc doesn't seem to optimize that.

The previous function body is the original implementation: ad8652818a5

```
// Before: 0.267s, after: 0.265s
function test_switch($x) {
    for ($i = 0; $i < 10000000; $i++) {
        switch ($x) {
        case 'a':
        case 'b':
            echo "i=$i\n";
        }
    }
}
test_switch(null);
```
