2025-12-29	Implement moving Immix in MMTk	Peter Zhu
	This commit implements moving Immix in MMTk, which allows objects to move in the GC. The performance of this implementation is not yet amazing. It is very similar to non-moving Immix in many of them and slightly slower in others. The benchmark results is shown below. -------------- ----------------- ---------- --------- bench Moving Immix (ms) stddev (%) RSS (MiB) activerecord 241.9 0.5 86.6 chunky-png 447.8 0.8 74.9 erubi-rails 1183.9 0.8 136.1 hexapdf 1607.9 2.6 402.3 liquid-c 45.4 6.7 44.9 liquid-compile 44.1 9.3 53.0 liquid-render 105.4 4.5 55.9 lobsters 650.1 9.7 418.4 mail 115.4 2.1 64.4 psych-load 1656.8 0.8 43.6 railsbench 1653.5 1.3 149.8 rubocop 127.0 15.6 142.1 ruby-lsp 130.7 10.5 99.4 sequel 52.8 7.2 45.6 shipit 1187.0 3.9 311.0 -------------- ----------------- ---------- --------- -------------- --------------------- ---------- --------- bench Non-moving Immix (ms) stddev (%) RSS (MiB) activerecord 218.9 2.7 86.1 chunky-png 464.6 0.8 66.7 erubi-rails 1119.0 4.3 132.7 hexapdf 1539.8 1.8 425.2 liquid-c 40.6 6.9 45.2 liquid-compile 40.6 8.1 52.9 liquid-render 99.3 2.3 48.3 mail 107.4 5.3 65.4 psych-load 1535.6 1.0 39.5 railsbench 1565.6 1.1 149.6 rubocop 122.5 14.3 146.7 ruby-lsp 128.4 10.7 106.4 sequel 44.1 4.0 45.7 shipit 1154.5 2.7 358.5 -------------- --------------------- ---------- ---------
