zend_compile: Optimize arguments for ZEND_NEW

[TimWolla]

Apply the optimization for static method calls to new calls, since new is effectively a static method for all intents and purposes.

For:

<?php

final class MyClass
{
	private function __construct(
		private \Random\Engine $foo,
		private int $bar = 0,
	) {}

	public static function new(int $bar): self
	{
		$engine = new \Random\Engine\Xoshiro256StarStar(seed: 123);
		return new self(foo: $engine, bar: $bar);
	}
}

for ($i = 0; $i < 3_000_000; $i++) {
	MyClass::new($i);
}

This is ~1.13 faster for a gcc 13.3 release build on a Intel(R) Core(TM) i7-1365U.

Benchmark 1: /tmp/bench/php.old /tmp/bench/test6.php
  Time (mean ± σ):     409.5 ms ±   1.9 ms    [User: 406.6 ms, System: 2.2 ms]
  Range (min … max):   407.4 ms … 414.0 ms    10 runs

Benchmark 2: /tmp/bench/php.new /tmp/bench/test6.php
  Time (mean ± σ):     360.9 ms ±   1.7 ms    [User: 358.5 ms, System: 2.2 ms]
  Range (min … max):   359.2 ms … 365.0 ms    10 runs

Summary
  /tmp/bench/php.new /tmp/bench/test6.php ran
    1.13 ± 0.01 times faster than /tmp/bench/php.old /tmp/bench/test6.php

Can this be tested somehow? (like opcache dump or so?)

[arnaud-lb]

Looks good to me!

I would also like to see an opcache test, as this is simple enough to verify. LGTM otherwise.

Okay, test added.
