pcntl_signal for SIGILL/SIGFPE/SIGSEGV/SIGBUS should add addr as int or string, not double

Description

add_assoc_double_ex is called in combination with a cast to zend_long - add_assoc_long_ex may have been intended? (There's one question about what's best for how negative zend_longs should be handled (high bit of pointer set), where pointers aren't actually negative) - keeping them negative seems better than sometimes using an int and sometimes using a string.

Motivation: Use 64-bit integers when it can properly represent the value. Don't use doubles when they might lose precision (e.g. virtual memory may allow numbers over the largest integer a double can safely represent?)
(not a priority for me, I'm just really surprised to see a float)

The following code:

<?php // Hackish example of a proof of concept userland signal handler to debug in an emergency,
// note that running any php snippets may fail again or have unexpected effects if php has already segfaulted
pcntl_signal(SIGSEGV, function (...$args) {
    echo "In signal handler\n";
    flush();
    var_dump($args);
    flush();
    debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);
    flush();
    exit(139);
});
pcntl_async_signals(true);
sleep(20);
// call 'kill -USR1 PID_OF_PHP' to attempt to simulate a segfault

// ext/pcntl/pcntl.c
			case SIGILL:
			case SIGFPE:
			case SIGSEGV:
			case SIGBUS:
				add_assoc_double_ex(user_siginfo, "addr", sizeof("addr")-1, (zend_long)siginfo->si_addr);
				break;

Resulted in this output:

In signal handler
array(2) {
  [0]=>
  int(11)
  [1]=>
  array(4) {
    ["signo"]=>
    int(11)
    ["errno"]=>
    int(0)
    ["code"]=>
    int(0)
    ["addr"]=>
    float(4294967486499)
  }
}
#0  {closure}(11, Array ([signo] => 11,[errno] => 0,[code] => 0,[addr] => 4294967486499)) called at [/usr/local/tyson/php-src/test.php:12]

But I expected this output instead on 64-bit platforms:

    ["addr"]=>
    int(4294967486499)

Comienza en ext/pcntl/pcntl.c con el manejo de SIGILL, SIGFPE, SIGSEGV y SIGBUS mostrado en el issue y, después, ejecuta el ejemplo proporcionado de un manejador de señales de PHP en una plataforma de 64 bits. Se considera terminado cuando el valor addr se representa como un entero cuando puede representarse de forma segura, en lugar de como un double; el issue también deja pendiente resolver el manejo de un zend_long negativo para punteros con el bit más alto establecido.
