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);
```

Revert "Fetch for read in nested property assignments"

This reverts commit bb43a3822e42dbd15b1d416a166549d3980b379a.

After thinking about this a bit more, this is now going to be
a complete solution for the "readonly properties" case, for example:

unset($foo->readOnly->bar);

should also be legal and

$foo->readOnly['bar'] = 42;

should also be legal if $foo->readOnly is not an array but an
ArrayAccess object.

I think it may be better to distinguish better on the BP_VAR flag
level. Reverting for now.

Fetch for read in nested property assignments

$a->b->c = 'd';

is now compiled the same way as

$b = $a->b;
$b->c = 'd';

That is, we perform a read fetch on $a->b, rather than a write
fetch.

This is possible, because PHP 8 removed auto-vivification support
for objects, so $a->b->c = 'd' may no longer modify $a->b proper
(i.e. not counting interior mutability of the object).
