gen: Cast constants to uint64_t for 64-bit data items

Global arrays with 64-bit integers would only have the 32 least
significant bits emitted in the data items. A declaration like:

	const _K: [_]u64 = [0x428a2f98d728ae22];

would result in:

	data section ".data._K" $_K = { l 3609767458 }

where it should have been 4794697086780616226.

The fix was suggested by Armin Weigl.
