Log:	(arigo, bivab): simple fix for a hard to track issue. When compiling
	a label we were keeping the stacklocation of prevously spilled
	floats that were loaded in a reg when we hit the label. When jumping
	from somewehere else to the label the float value in the register is
	forgotten, because it is assumed to be on the stack too.
