Static class cache benchmark

This benchmark contains isolated reads and writes of statically resolved self::$property and Class::$property slots. It also covers a common metadata-cache pattern: a static array keyed by static::class, guarded by isset(), plus a wrapper method using static::method(). The latter measures static-property lookup, array lookup, strict return checks, and late-static dispatch together.

Run it from the repository root against matching Release PHP and PHPX builds:

PHPX_HOME=../phpx PHP_BIN=/opt/php-8.5-nts/bin/php php benchmark/static-cache/run.php

The TypePHP binary is built with -O3 and LTO. Results use the best of five measured rounds after two warm-up rounds; checksums must match before ratios are reported. Use --skip-build to reuse the existing binary.
