predcom: Fix up component::component [PR105056]

The recent change didn't initialize comp_step while previously we used
XCNEW to allocate it.

I think RS_ANY is better than RS_INTERNAL (== 0) as the default.

	PR tree-optimization/105056
	* tree-predcom.cc (component::component): Initialize also comp_step.
