Optimize swc_ecma_transforms_base::Helpers

[kdy1]

Describe the feature

swc/crates/swc_ecma_transforms_base/src/helpers/mod.rs

Lines 144 to 146 in daf1025

	struct Inner {
	$( $name: AtomicBool, )*
	}

Currently, we use AtomicBool for tracking used helpers, but we can use bool instead. We can merge by performing || on each fields while passing it to another thread.

We also need to patch code at

swc/crates/swc_ecma_transforms_base/src/perf.rs

Lines 172 to 210 in daf1025

	HELPERS.with(|helpers| {
	HANDLER.with(|handler| {
	nodes
	.into_par_iter()
	.map(|node| {
	GLOBALS.set(globals, || {
	HELPERS.set(helpers, || {
	HANDLER.set(handler, || {
	let mut visitor = Parallel::create(&*self);
	let node = node.fold_with(&mut visitor);
	(visitor, node)
	})
	})
	})
	})
	.fold(
	|| (Parallel::create(&*self), vec![]),
	|mut a, b| {
	Parallel::merge(&mut a.0, b.0);
	a.1.push(b.1);
	a
	},
	)
	.reduce(
	|| (Parallel::create(&*self), vec![]),
	|mut a, b| {
	Parallel::merge(&mut a.0, b.0);
	a.1.extend(b.1);
	a
	},
