[php-src] Issue #21949: Bug with JIT / Opcache on float / int calculation

Issue: https://github.com/php/php-src/issues/21949
Author: ahfeel

### Description

The following code:

```php
<?php

function calculateHealthScore(float $p, int $s): int
{
    if ($p === 0.0) {
        return 0;
    }

    $partnerIncreasedSales = $s * 1.5;

    if ($p + $partnerIncreasedSales < 0) {
        return (int) round(($partnerIncreasedSales / abs($p)) * 100);
    }

    return 100;
}

$x = unserialize(file_get_contents('vars.txt'));

foreach ($x as $affiliateId => $affiliateStats) {
    $x[$affiliateId]['health'] = calculateHealthScore(
        $x[$affiliateId]['profitability'],
        $x[$affiliateId]['sales_nb']
    );
}

var_dump($x[2376086]);
```

Resulted in this output *ON THE FIRST RUN*:
```
array(4) {
  ["sales_nb"]=>
  string(1) "7"
  ["affiliate"]=>
  int(2376086)
  ["profitability"]=>
  string(6) "-13.45"
  ["health"]=>
  int(78)
}
```

Then resulted in this output *ON THE SECOND RUN*
```
Resulted in this output *ON THE FIRST RUN*:
```
array(4) {
  ["sales_nb"]=>
  string(1) "7"
  ["affiliate"]=>
  int(2376086)
  ["profitability"]=>
  string(6) "-13.45"
  ["health"]=>
  int(0)
}
```

But I expected this output instead:
```
array(4) {
  ["sales_nb"]=>
  string(1) "7"
  ["affiliate"]=>
  int(2376086)
  ["profitability"]=>
  string(6) "-13.45"
  ["health"]=>
  int(78)
}
```

When running again with the -d opcache.jit=0 option:
```
array(4) {
  ["sales_nb"]=>
  string(1) "7"
  ["affiliate"]=>
  int(2376086)
  ["profitability"]=>
  string(6) "-13.45"
  ["health"]=>
  int(78)
}
```

Changing the $p parameter from float to string fixes the issue :-/
