getClaimStatement uses class as object property name

[jacobmischka]

Another lame IE9 problem...

It appears that getClaimStatement is using class as a property name when constructing the attributes object. This causes an error in IE9.

svelte/src/generators/dom/visitors/Element/Element.ts

Lines 241 to 257 in ad59771

	function getClaimStatement(
	generator: DomGenerator,
	namespace: string,
	nodes: string,
	node: Node
	) {
	const attributes = node.attributes
	.filter((attr: Node) => attr.type === 'Attribute')
	.map((attr: Node) => `${quoteProp(attr.name)}: true`)
	.join(', ');
	const name = namespace ? node.name : node.name.toUpperCase();
	return `@claimElement(${nodes}, "${name}", ${attributes
	? `{ ${attributes} }`
	: `{}`}, ${namespace === namespaces.svg ? true : false})`;
	}

Hm for what it's worth it seems like IE9 should allow this as is, not sure what's wrong with my IE9 vm that's making it error here.
